我使用ActionBarDrawerToggle来打开和关闭DrawerLayout。 但是我的drawerlayout中的listView没有显示。
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setBackgroundColor(getResources().getColor(R.color.abs__background_holo_light));
mDrawerList.setAdapter(menuAdapter);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_navigation_drawer,
R.string.open, R.string.close) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
它只显示没有条目的黑色抽屉。 drawerList应为“setBackgroundColor”中设置的白色,drawerList应显示适配器的条目。
当我使用openDrawer(mDrawerList)打开抽屉时,它可以正常工作,但不能轻扫。
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;
//}
switch (item.getItemId()) {
case android.R.id.home:
if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
mDrawerLayout.closeDrawer(mDrawerList);
} else {
mDrawerLayout.openDrawer(mDrawerList);
}
break;
这是带有DrawerLayout的main.xml布局:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- The main content -->
<fragment
android:id="@+id/activeRemindersList"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
class="com.colapps.reminder.fragments.ActiveRemindersFragment" />
<!-- The navigation drawer -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" />
有人可以帮忙吗?
更新
问题似乎是片段。 如果我添加而不是Fragment一个简单的FrameLayout一切正常工作:
<!-- The main content -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test" />
</FrameLayout>
<!-- The navigation drawer -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" />

问题解决了!
问题在于Fragment Layout也是一个“DrawerLayout”。
我已经改变了很多,忘记将它从片段布局中删除。
感谢所有试图帮助我的人。

我很确定这与之有关:
尝试更改layot文件,以便ListView也具有权重属性并更改Fragment的height属性。此外,将它们都放在 LinearLayout 。
中同时确保您在“活动”中覆盖了这些方法:
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
@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);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this.
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
} else
return false;
}

使用onDrawerItemSelected(int pos)
方法添加/替换片段。
@Override
public void onDrawerItemSelected(int pos) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (pos) {
case 0:
fragment = new FragOne();
break;
case 1:
fragment = new FragTwo();
break;
case 2:
fragment = new FragThree();
break;
}
// R.id.content_frame is the id of the FrameLayout
getFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit()
// update selected item then close the drawer
mDrawerList.setItemChecked(pos, true);
mDrawerLayout.closeDrawer(mDrawerList);
}
这里有一个关于如何实现NavigationDrawer的详细教程/示例。当我第一次使用NavigationDrawer时,我阅读了本教程,并且能够成功实现它。

我认为你在XML中缺少<FrameLayout>
(注意我已经包装片段内容的那个)。
看起来应该是这样的:
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent" >
<FrameLayout
android:id="@+id/main"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="@+id/app_info_fragment_phone"
... />
</FrameLayout>
<ListView
android:id="@+id/drawer"
... />
</android.support.v4.widget.DrawerLayout>
