我有一个新的应用程序,实际上我的第一个应用程序,我想显示导航抽屉。
应用程序运行正常并在用户登录远程服务器后显示用户配置文件。
抽屉工作正常,按预期打开和关闭。
但是应该有一个动作栏。而且我没有看到它。此外,也没有汉堡包抽屉图标。
正常加载的用户个人资料类,显示用户个人资料数据:
public class UserProfileActivity extends UserActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
}
}
用户活动是所有用户活动的基类:
public class UserActivity extends BaseActivity {
private String email;
private String token;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user);
setupDrawer();
}
}
最后是基础活动:
public class BaseActivity extends AppCompatActivity {
private Toolbar toolbar;
private ActionBarDrawerToggle drawerToggle;
private DrawerLayout baseLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkVersion();
}
@Override
public void setContentView(int layoutResID) {
baseLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.base, null);
FrameLayout contentLayout = (FrameLayout) baseLayout.findViewById(R.id.content);
getLayoutInflater().inflate(layoutResID, contentLayout, true);
super.setContentView(baseLayout);
// Set a Toolbar to replace the ActionBar
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (null != toolbar) {
setSupportActionBar(toolbar);
}
ActionBar actionBar = getSupportActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
drawerToggle = new ActionBarDrawerToggle(this, baseLayout, toolbar , R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
//getActionBar().setTitle(mTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
//getActionBar().setTitle(mDrawerTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
baseLayout.setDrawerListener(drawerToggle);
baseLayout.post(new Runnable() {
@Override
public void run() {
drawerToggle.syncState();
}
});
}
adb logcat显示工具栏不为null:

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
layout="@layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
这是布局的相关部分。您的Toolbar
和FrameLayout
都在RelativeLayout
范围内。 FrameLayout
只是覆盖在Toolbar
上,覆盖它。
将RelativeLayout
替换为LinearLayout
或将FrameLayout
置于工具栏下方(RelativeLayout
内),如
<include
android:id="@+id/toolbarinclude"
layout="@layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:layout_below="@id/toolbarinclude"
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
