（1）github

以下是RxBing的github地址：

目前RxBinding已经更新到3.0.0-alpha2了。

（2）依赖

RxBinding2.0.0使用量比较多：

implementation 'com.jakewharton.rxbinding2:rxbinding:2.0.0'

RxBinding2.2.0之后废弃了一些组件和接口

implementation 'com.jakewharton.rxbinding2:rxbinding:2.2.0'

另外RxBinding2.2.0提供了对recyclerview组件的扩展

implementation 'com.jakewharton.rxbinding2:rxbinding-recyclerview-v7:2.2.0'

如果用到recyclerview的话可以选择使用 recyclerview-v7:2.2.0这个依赖。

RxBinding现在已经更新到3.0.0了：

我们可以使用以下依赖

implementation 'com.jakewharton.rxbinding3:rxbinding:3.0.0-alpha2'

同时，在2.0.0的基础上废弃了不少接口。

RxBinding3.0.0加入了对AndroidX的支持

implementation 'com.jakewharton.rxbinding3:rxbinding-core:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-appcompat:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-drawerlayout:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-leanback:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-recyclerview:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-slidingpanelayout:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-swiperefreshlayout:3.0.0-alpha2'
implementation 'com.jakewharton.rxbinding3:rxbinding-viewpager:3.0.0-alpha2'

包括Google 'material' library bindings:

implementation 'com.jakewharton.rxbinding3:rxbinding-material:3.0.0-alpha2'

也需要AndroidX的支持。

随着Android SDK版本的迭代，api28之后将不再更新，将传统项目转成AndoridX刻不容缓，RxBinding对AndroidX的支持以后应该还会继续迭代。

本章将针对

implementation 'com.jakewharton.rxbinding3:rxbinding:3.0.0-alpha2'

这个依赖包进行分析。

还有一点需要说明，如果项目中已经导入了以下依赖包，可以直接删除了，因为RxBinding的依赖包自带rxjava和rxandroid。

implementation 'io.reactivex.rxjava2:rxjava:2.1.3'
implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'

（3）相关组件

RxAbsListView、RxAdapter、RxAdapterView、RxAutoCompleteTextView、RxCompoundButton、RxPopupMenu、RxRadioGroup、RxRatingBar、RxSearchView、RxSeekBar、RxTextView、RxToolbar、RxMenuItem、RxView、RxViewGroup

（4）RxView

clicks 点击事件

  RxView.clicks(bt_1).subscribe(new Consumer<Object>() {
      @Override
      public void accept(Object o) throws Exception {
          Log.d("aaa", "点击事件");
      }
  });

相当于

    bt_1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("aaa", "点击事件");
        }
    });

visibility 隐藏或者显示

方法一：

    boolean value = false;
    try {
        RxView.visibility(bt_1).accept(value);
    } catch (Exception e) {
        e.printStackTrace();
    }

相当于

    boolean value = false;
    bt_1.setVisibility(value ? View.VISIBLE : View.GONE);

方法二：

    boolean value = false;
    int visibilityWhenFalse = View.VISIBLE;

    try {
        RxView.visibility(bt_1, visibilityWhenFalse).accept(value);
    } catch (Exception e) {
        e.printStackTrace();
    }

相当于

    boolean value = false;

                  Log.d("aaa", "1111111111111111");
              }
          });

相当于

    bt_1.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {

            return false;
        }
    });

attachEvents View被添加时触发

RxView.attachEvents(bt_1)

detaches View被移除

RxView.detaches(bt_1);

drags 拖拽的监听

  RxView.drags(ll_demo)
          .subscribe(new Consumer<DragEvent>() {
              @Override
              public void accept(DragEvent event) throws Exception {
                  //获取事件
                  int action = event.getAction();
                  switch (action) {
                      case DragEvent.ACTION_DRAG_STARTED:
                          Log.d("aaa", "开始拖拽");
                          break;
                      case DragEvent.ACTION_DRAG_ENDED:
                          Log.d("aaa", "结束拖拽");
                          break;
                      case DragEvent.ACTION_DRAG_ENTERED:
                          Log.d("aaa", "拖拽的view进入监听的view时");
                          break;
                      case DragEvent.ACTION_DRAG_EXITED:
                          Log.d("aaa", "拖拽的view离开监听的view时");
                          ll_demo.setBackgroundColor(Color.parseColor("#303F9F"));
                          break;
                      case DragEvent.ACTION_DRAG_LOCATION:
                          float x = event.getX();
                          float y = event.getY();
                          ll_demo.setBackgroundColor(Color.GRAY);
                          Log.i("aaa", "拖拽的view在监听view中的位置:x =" + x + ",y=" + y);
                          break;
                      case DragEvent.ACTION_DROP:
                          Log.i("aaa", "释放拖拽的view");

                          if(event != null && event.getLocalState() != null){
                              View localState = (View) event.getLocalState();
                              FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                              ((ViewGroup) localState.getParent()).removeView(localState);
                              ll_demo.addView(localState, layoutParams);
                          }
                          break;
                  }
              }
          });

    RxView.longClicks(bt_1)
            .subscribe(new Consumer<Unit>() {
                @Override
                public void accept(Unit unit) throws Exception {

                    //设置震动反馈
                    bt_1.performHapticFeedback(HapticFeedbackConstants.LONG_PRESS, HapticFeedbackConstants.FLAG_IGNORE_GLOBAL_SETTING);

                    // 创建DragShadowBuilder，我把控件本身传进去
                    View.DragShadowBuilder builder = new View.DragShadowBuilder(bt_1);
                    // 剪切板数据，可以在DragEvent.ACTION_DROP方法的时候获取。
                    ClipData data = ClipData.newPlainText("Label", "我是文本内容！");
                    // 开始拖拽
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                        bt_1.startDragAndDrop(data, builder,bt_1, 0);
                    }else{
                        bt_1.startDrag(data, builder, bt_1, 0);
                    }

                }
            });

效果如下：

draws 重绘监听

监听某View重绘

随便自定义一个view吧

public class CustomView extends View {
    public CustomView(Context context) {
        super(context);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr, 0);
    }

    int[] colors = {Color.RED, Color.BLACK, Color.CYAN, Color.BLUE};
    int index = 0;
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        canvas.drawColor(colors[index]);
        Log.d("aaa", String.valueOf(index));

        index = (++index >= colors.length) ? 0 : index;
        postInvalidateDelayed(1000);
    }
}

效果如下

现在开始监听

            RxView.draws(view_demo)
                    .subscribe(new Consumer<Unit>() {
                        @Override
                        public void accept(Unit unit) throws Exception {
                            Log.d("aaa", "22222");
                        }
                    });

相当于

            view_demo.getViewTreeObserver().addOnDrawListener(new ViewTreeObserver.OnDrawListener() {
                @Override
                public void onDraw() {
                    Log.d("aaa", "22222");
                }
            });

globalLayouts 监听布局改变

在弹出软键盘，使布局变化的场景常用

    RxView.globalLayouts(rootview)
            .subscribe(new Consumer<Unit>() {
                @Override
                public void accept(Unit unit) throws Exception {
                    Log.d("aaa", "1111111111111111111");
                }
            });

相当于

    rootview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            Log.d("aaa", "1111111111111111111");
        }
    });

focusChanges 监听焦点变化

  RxView.focusChanges(et_demo)
          .subscribe(new Consumer<Boolean>() {
              @Override
              public void accept(Boolean aBoolean) throws Exception {
                  Log.d("aaa", "11111111111111");
              }
          });

相当于

    et_demo.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            Log.d("aaa", "11111111111111");
        }
    });

hovers 悬停事件

一些平板支持鼠标，当鼠标悬停在某view上时，会有其他效果

图片.png

比如给按钮添加背景，设置state_hovered属性，当鼠标悬停在view上时会改变颜色。

我们也可以对悬停事件进行监听

    RxView.hovers(bt_1)
            .subscribe(new Consumer<MotionEvent>() {
                @Override
                public void accept(MotionEvent motionEvent) throws Exception {
                    Log.d("aaa", "11111111111111");
                    int what = motionEvent.getAction();
                    switch(what){
                        case MotionEvent.ACTION_HOVER_ENTER: //鼠标进入view
                            break;
                        case MotionEvent.ACTION_HOVER_MOVE: //鼠标在view上
                            break;
                        case MotionEvent.ACTION_HOVER_EXIT: //鼠标离开view
                            break;
                    }
                }
            });

相当于

    bt_1.setOnHoverListener(new View.OnHoverListener() {
        @Override
        public boolean onHover(View v, MotionEvent event) {
            Log.d("aaa", "11111111111111");
            int what = event.getAction();
            switch(what){
                case MotionEvent.ACTION_HOVER_ENTER: //鼠标进入view
                    break;
                case MotionEvent.ACTION_HOVER_MOVE: //鼠标在view上
                    break;
                case MotionEvent.ACTION_HOVER_EXIT: //鼠标离开view
                    break;
            }
            return false;
        }
    });

keys 按键被按下

主要用作于监听物理按键的返回键，当然，软键盘的删除和回车(搜索)也是可以监听到的。

    RxView.keys(et_demo)
            .subscribe(new Consumer<KeyEvent>() {
                @Override
                public void accept(KeyEvent keyEvent) throws Exception {
                    Log.d("aaa", "11111111111111");
                }
            });

相当于

    et_demo.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            Log.d("aaa", "11111111111111:"+event.getAction());
            return false;
        }
    });

layoutChanges和layoutChangeEvents 组件布局参数发生改变

  RxView.layoutChanges(rootview)
          .subscribe(new Consumer<Unit>() {
              @Override
              public void accept(Unit unit) throws Exception {
                  Log.d("aaa", "1111111111111111111");
              }
          });

    RxView.layoutChangeEvents(rootview)
            .subscribe(new Consumer<ViewLayoutChangeEvent>() {
                @Override
                public void accept(ViewLayoutChangeEvent viewLayoutChangeEvent) throws Exception {
                    Log.d("aaa", "1111111111111111111");
                }
            });

相当于

    rootview.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
        @Override
        public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
            Log.d("aaa", "1111111111111111111");
        }
    });

preDraws 将要绘制时

熟悉自定义view或者viewgroup的猿一定知道三个方法：onMeasure、onLayout、onDraw，它们的执行顺序是onMeasure-->onLayout-->onDraw， preDraws监听的时机就在onLayout和onDraw之间。

    RxView.preDraws(view_demo, new Function0<Boolean>() {
        @Override
        public Boolean invoke() {
            return false;
        }
    })
            .subscribe(new Observer<Unit>() {
                @Override
                public void onSubscribe(Disposable d) {
                    disposable = d;
                }

                @Override
                public void onNext(Unit unit) {
                    Log.d("aaa", "onPreDraw");
                    //接收一次之后立即移除监听，否则会阻塞UI线程
                    disposable.dispose();
                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onComplete() {

                }
            });

相当于

    view_demo.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
        @Override
        public boolean onPreDraw() {
            Log.d("aaa", "onPreDraw");
            //监听一次之后立即移除监听，否则会阻塞UI线程
            view_demo.getViewTreeObserver().removeOnPreDrawListener(this);
            return false;
        }
    });

scrollChangeEvents 滚动事件API23

这个监听在API 23之后生效

    RxView.scrollChangeEvents(view_demo)
            .subscribe(new Consumer<ViewScrollChangeEvent>() {
                @Override
                public void accept(ViewScrollChangeEvent viewScrollChangeEvent) throws Exception {
                    
                }
            });

相当于

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        view_demo.setOnScrollChangeListener(new View.OnScrollChangeListener() {
            @Override
            public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {

            }
        });
    }

systemUiVisibilityChanges 状态栏和导航栏可见和隐藏

  RxView.systemUiVisibilityChanges(rootview)
          .subscribe(new Consumer<Integer>() {
              @Override
              public void accept(Integer integer) throws Exception {
                  
              }
          });

相当于

    rootview.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
        @Override
        public void onSystemUiVisibilityChange(int visibility) {

        }
    });

touches 触摸事件

  RxView.touches(et_demo)
          .subscribe(new Consumer<MotionEvent>() {
              @Override
              public void accept(MotionEvent motionEvent) throws Exception {
                  
              }
          });

相当于

    et_demo.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
        }
    });

（5）RxTextView

beforeTextChangeEvents、textChanges、textChangeEvents、afterTextChangeEvents

对文本变化监听。

    RxTextView.beforeTextChangeEvents(et_demo)
            .subscribe(new Consumer<TextViewBeforeTextChangeEvent>() {
                @Override
                public void accept(TextViewBeforeTextChangeEvent textViewBeforeTextChangeEvent) throws Exception {
                    Log.d("aaa", "111111111111111");
                }
            });

    RxTextView.textChangeEvents(et_demo)
            .subscribe(new Consumer<TextViewTextChangeEvent>() {
                @Override
                public void accept(TextViewTextChangeEvent textViewTextChangeEvent) throws Exception {
                    Log.d("aaa", "2222222222222222222");
                }
            });
