Question

我已经在我的应用程序中使用了一个图标调整了导航抽屉，如图1所示，似乎没问题。我想在谷歌地图的右侧底部显示图标。

代码：

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

private void setupSlideMenu() {
    mPlanetTitles = getResources().getStringArray(R.array.planets_array);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout1);
    addIcon();
    mDrawerList = (ListView) findViewById(R.id.left_drawer1);

    // Set the adapter for the list view
    mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mPlanetTitles));
    // Set the list's click listener
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
    log("setupSlideMenu", false);
}

private void addIcon() {
    mDrawerToggle = new ActionBarDrawerToggle(
    this,                   /* host Activity */
    mDrawerLayout,          /* DrawerLayout object */
    R.drawable.ic_drawer,   /* nav drawer icon to replace 'Up' caret */
    R.string.drawer_open,   /* "open drawer" description */
    R.string.drawer_close   /* "close drawer" description */
    ) {
        /** Called when a drawer has settled in a completely closed state. */
        public void onDrawerClosed(View view) {
            getActionBar().setTitle(mTitle);
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            getActionBar().setTitle(mDrawerTitle);
        }
    };
    // Set the drawer toggle as the DrawerListener
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Pass the event to ActionBarDrawerToggle, if it returns true, then it has handled the app icon touch event
    if (mDrawerToggle.onOptionsItemSelected(item)) {
      return true;
    }
    // Handle your other action bar items...
    return super.onOptionsItemSelected(item);
}

有什么想法吗？提前谢谢！

使用BottomDrawerToggle。解决方案非常简单：

使用重力BOTTOM将<{1}}添加到android.R.id.content FrameLayout
通过将右/左边距设置为其可绘制宽度的一半的负值，使ImageView一半可见。
已解析的内部资源ImageView并将其用作图片视图的底部填充
```
action_bar_icon_vertical_padding
```
创建了int id = Resources.getSystem().getIdentifier("action_bar_icon_vertical_padding", "dimen", "android"); float padding = mActivity.getResources().getDimension(id);并计算了当抽屉在SlidingDrawable方法中滑入/滑出时如何动态隐藏drawable。通过使用抽屉的可见像素量剪切draw(Canvas canvas)来隐藏Drawable。
```
Rect
```
