Android 界面侧滑

DrawableLayout 抽屉布局

在activity布局文件中加入DrawableLayout控件

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/main_drawer"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:textSize="20sp"
            android:textStyle="bold"
            android:text="第一个TextView里面的内容"
            android:background="@color/colorPrimary"/>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:textSize="20sp"
            android:textStyle="bold"
            android:layout_gravity="start|left"
            android:text="第二个TextView里面的内容"
            android:background="@color/colorAccent"/>
    </android.support.v4.widget.DrawerLayout>
  • 这里第一个TextView为显示界面,第二个TextView是抽屉可拉伸;
  • 第二个TextView设置的layout_gravity表明了抽屉的拉出位置

抽屉侧滑结合ActionBar 的左侧按钮

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mDrawer = (DrawerLayout) findViewById(R.id.main_drawer);
    ActionBar actionBar = getSupportActionBar();
    actionBar.setTitle("ActionBar");
    actionBar.setDisplayHomeAsUpEnabled(true);
    mToggle = new ActionBarDrawerToggle(this,mDrawer,0,0);
    mDrawer.addDrawerListener(mToggle);
    mToggle.syncState();
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    mToggle.onOptionsItemSelected(item);
    return super.onOptionsItemSelected(item);
}
  • 这里使用activity默认的ActionBar
  • 获取ActionBar设置标题 --> 设置左侧按钮可用
  • 创建ActionBarDrawerToggle对象,抽屉的触发器,开关
  • 抽屉关联开关mDrawer.addDrawerListener(mToggle); --> 抽屉的动作会影响开关
  • 开关同步抽屉状态mToggle.syncState(); --> 点击开关会影响抽屉

抽屉侧滑结合Toolbar

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mToolbar = (Toolbar) findViewById(R.id.main_toolbar);
    mDrawer = (DrawerLayout) findViewById(R.id.main_drawer);
    setSupportActionBar(mToolbar);
    ActionBar actionBar = getSupportActionBar();
    mToggle = new ActionBarDrawerToggle(this,mDrawer,mToolbar,0,0);
    mDrawer.addDrawerListener(mToggle);
    mToggle.syncState();
} 
  • 需要改写activity的Theme设置为NoActionBar

SlidingPaneLayout

GroupView的子类

android.support.v4.widget.SlidingPaneLayout

创建BaseActivity让所有的Activity都具有侧滑放回功能。

创建BaseActivity

布局文件:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/base_sliding"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.doublefang.slidingpanelayoutdemo.BaseActivity">

    <View
        android:id="@+id/base_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?actionBarSize"/>

        <FrameLayout
            android:id="@+id/base_content"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"/>
    </LinearLayout>

</android.support.v4.widget.SlidingPaneLayout>
  • 第一个View为滑动的后页面
  • 第二个LinearLayout是正常展示界面
  • 这里的FrameLayoutActivity站位
  • android:layout_weight="1"

BaseActivity代码:

public class BaseActivity extends AppCompatActivity implements SlidingPaneLayout.PanelSlideListener {

    private Toolbar mToolbar;
    private SlidingPaneLayout mSliding;
    private FrameLayout mContent;
    private View mPanel;

//    private boolean slidable = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setContentView(R.layout.activity_base);
//        setTheme(R.style.MyTheme);
        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar);
        mSliding = (SlidingPaneLayout) findViewById(R.id.base_sliding);
        mSliding.setPanelSlideListener(this);
        mSliding.setSliderFadeColor(0);
        mContent = (FrameLayout) findViewById(R.id.base_content);
        mPanel = findViewById(R.id.base_view);
    }

    @Override
    public void setContentView(@LayoutRes int layoutResID) {
        View view = LayoutInflater.from(this).inflate(layoutResID, mContent, false);
        setContentView(view);
    }

    @Override
    public void setContentView(View view) {
        view.setBackgroundColor(Color.WHITE);
        mContent.addView(view);
    }

    @Override
    public void setContentView(View view, ViewGroup.LayoutParams params) {
        view.setBackgroundColor(Color.WHITE);
        mContent.addView(view);
    }

    @Override
    public void onPanelSlide(View panel, float slideOffset) { }

    @Override
    public void onPanelOpened(View panel) {
        finish();
    }

    @Override
    public void onPanelClosed(View panel) { }

    public void setSlidable(boolean flag) {
//        this.slidable = flag;
        if (!flag)  mSliding.removeView(mPanel);
    }
}
  • 滑动切换界面的时候默认是上面的界面会变透明,设置取消透明mSliding.setSliderFadeColor(0);
  • view.setBackgroundColor(Color.WHITE);防止正常显示的界面透明

定制AppTheme

<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowAnimationStyle">@style/WindowAnimation</item>
</style>

<style name="WindowAnimation">
    <item name="android:activityOpenEnterAnimation">@android:anim/slide_in_left</item>
    <item name="android:activityCloseExitAnimation">@android:anim/slide_out_right</item>
</style>
  • NoActionBar
  • 设置窗口为透明,如果View控件没有设置背景那就是透明的
  • 设置动画:默认活动是从底部出现。
