    策略一: 使用原生toolbar进行封装

    流程:

    * 1所有的类都继承此AppToolBarActivity.
    
    * 2打气筒加载一个布局到根布局(即layout_toolbar),此布局包含ToolBar+Framelayout.
    
    * 3getContentView()为抽象方法,返回一个View 将此View add到framelayout中.
    
    * 4做一些ToolBar的初始化操作.
    
    * 5使用
    
        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            View view = LayoutInflater.from(this).inflate(R.layout.layout_toolbar, (ViewGroup) getWindow().getDecorView().getRootView(), false);
            mContent_frame = view.findViewById(R.id.content_frame);
            if(getContentView() != null){
                mContent_frame.addView(getContentView());
            }
            setContentView(view);
    
            ButterKnife.bind(this);
            steepTitle();
            setSupportActionBar(mToolbar);
            getSupportActionBar().setTitle("");
            getSupportActionBar().setDisplayHomeAsUpEnabled(true);
            getSupportActionBar().setDisplayShowHomeEnabled(true);
            setTitle(getTitle());
    
            initWidget();
            initData();
        }
    
    • 处理ToolBar的返回事件:
        //style.xml中
        <item name="android:homeAsUpIndicator">@mipmap/back_white</item>
        //AppToolBarActivity中
        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            if(item.getItemId() == android.R.id.home){
                onBackPressed();
            }
            return super.onOptionsItemSelected(item);
        }
    
    • 处理中间Title 重写setTitle()
        //bar 中间标题
        @Override
        public void setTitle(CharSequence title) {
            mToolbar_tv_title.setText(title);
            mRadioGroup.setVisibility(View.GONE);
        }   
    
    • 处理右侧可能是文字或图片按钮 中间可能是多按钮
        //bar右侧是文字
        protected void setRightTextButtonEnable(@StringRes int rid, View.OnClickListener onClickListener) {
            mTv_title_right.setText(rid);
            mTv_title_right.setOnClickListener(onClickListener);
            mTv_title_right.setVisibility(View.VISIBLE);
        }
        
        //bar右侧是图标
        protected void setRightImageButtonEnable(@DrawableRes int rid, View.OnClickListener onClickListener) {
            mIv_title_right.setImageResource(rid);
            mIv_title_right.setOnClickListener(onClickListener);
            mIv_title_right.setVisibility(View.VISIBLE);
            mTv_title_right.setVisibility(View.GONE);
    
        }
    
        //bar中间是多按钮
        protected void setCenterRadioGroupEnable(String btnLefttext,String btnRighttext, RadioGroup.OnCheckedChangeListener onClickListener) {
            mRadioBtnLeft.setText(btnLefttext);
            mRadioBtnRight.setText(btnRighttext);
            mRadioGroup.setOnCheckedChangeListener(onClickListener);
            mRadioGroup.setVisibility(View.VISIBLE);
            mToolbar_tv_title.setVisibility(View.GONE);
        }
        
    
    • 处理所谓的沉浸式
        //加载沉浸式状态栏
        public void steepTitle() {
            if (Build.VERSION.SDK_INT >= 21) {
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                //注意要清除 FLAG_TRANSLUCENT_STATUS flag
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
                getWindow().setStatusBarColor(getResources().getColor(R.color.maincolor));
            }
        }
       
    
    • 最后使用超简单:
        @Override
        protected View getContentView() {
            return initRId(R.layout.activity_main);
        }
    
        @Override
        protected void initWidget() {
            setBackEnable(false);
            setTitle("主页");
        }

    策略2:自己写一个Bar 使用重载方法初始化

    • 核心代码:
        protected void initAppBar() {
            initAppBar(true, false, -1, -1);
        }
    
        protected void initAppBar(boolean isBack) {
            initAppBar(isBack, false, -1, -1);
        }
    
        protected void initAppBar(boolean isBack, boolean isRightText) {
            initAppBar(isBack, isRightText, -1, -1);
        }
    
        protected void initAppBar(boolean isBack, boolean isRightText, @ColorRes int bgColor, @ColorRes int textColor) {
            //动态添加appbar 这样无需在每个xml中includ进去appbar的布局
            //如果不写这四行 需要在每个xml中incloud进去bar布局
            ViewGroup view = getWindow().getDecorView().findViewById(android.R.id.content);
            ViewGroup inflate = (ViewGroup) view.getChildAt(0);
            View barView = getLayoutInflater().inflate(R.layout.common_appbar, inflate,false);
            inflate.addView(barView,0);
    
            RelativeLayout layout = findViewById(R.id.common_appbar_rl);
            if (layout == null) {
                return;
            }
            invadeStatusBar();
            if (bgColor != -1) {
                layout.setBackgroundResource(bgColor);
            }
            LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) layout.getLayoutParams();
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                layoutParams.setMargins(0, getStatusBarHeight(), 0, 0);
            } else {
                layoutParams.setMargins(0, 0, 0, 0);
            }
            layout.setLayoutParams(layoutParams);
            ImageView iconIV = findViewById(R.id.common_appbar_iv);
            if (!isBack) {
                iconIV.setVisibility(View.GONE);
            } else {
                iconIV.setVisibility(View.VISIBLE);
                iconIV.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        finish();
                    }
                });
            }
            TextView centerTV = findViewById(R.id.common_appbar_center_tv);
            if (textColor != -1) {
                centerTV.setTextColor(getResources().getColor(textColor));
            }
            centerTV.setText(TypeUtil.isBlank(setAppBarTitle()) ? "" : setAppBarTitle());
            TextView rightTV = findViewById(R.id.common_appbar_right_tv);
            if (!isRightText) {
                rightTV.setVisibility(View.GONE);
            } else {
                rightTV.setVisibility(View.VISIBLE);
                if (textColor != -1) {
                    centerTV.setTextColor(getResources().getColor(textColor));
                }
                rightTV.setText(TypeUtil.isBlank(setAppBarRightTitle()) ? "" : setAppBarRightTitle());
                rightTV.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        onAppBarRightClick();
                    }
                });
            }
        }
    
    • 重载方法:
        protected abstract String setAppBarTitle();
    
        protected abstract String setAppBarRightTitle();
    
        protected abstract void onAppBarRightClick();
    
    • 使用:
      initAppBar(true,true);
    
      @Override
        protected String setAppBarTitle() {
            return "Tactics2";
        }
    
        @Override
        protected String setAppBarRightTitle() {
            return "更多";
        }
    
        @Override
        protected void onAppBarRightClick() {
            ToastUtil.showToast("更多");
        }
    

    最后安利一个小技巧:

    • Activity跳转时候,可以这么写,更舒服:
        //只需要在目标Activity敲下start 就会出现自带的方法,可以传递一些数据:
        public static void start(Context context, String id) {
            Intent starter = new Intent(context, TacticsOneActivity.class);
            starter.putExtra("id", id);
            context.startActivity(starter);
        }
    
        //在执行跳转的某按钮处,只需简短一句:
        XxxActivity.start(this,"1");
    
    • 同理Fragment:
        //只需要在目标Fragment敲下newI :
        public static ChargeRecordFragment newInstance(int type,String coinName,String coinDetailName) {
            Bundle args = new Bundle();
            args.putInt("type",type);
            args.putString("coinName",coinName);
            args.putString("coinDetailName",coinDetailName);
            ChargeRecordFragment fragment = new ChargeRecordFragment();
            fragment.setArguments(args);
            return fragment;
        }
        //Activity的某处拿到实例并传递数据:
        ChargeRecordFragment.newInstance(0,mCoinName,mCoinDetailName);
