[英]Android Navigation Drawer - Fragment Navigation not working properly
I have designed navigation drawer app. 我设计了导航抽屉应用程序。 All the other features are working properly except Fragment navigation. 除片段导航外,所有其他功能均正常工作。
When i try to select an item from the side menu, its displays that selected layout on top of the activity_main layout.I think transition.replace()
method is not working or it does not replacing the current layout with selected layout. 当我尝试从侧面菜单中选择一个项目时,它会在activity_main布局的顶部显示所选的布局。我认为transition.replace()
方法无法正常工作,或者无法将当前的布局替换为选定的布局。
Here is my code 这是我的代码
public class MainActivity extends FragmentActivity {
ActionBarDrawerToggle icon;
final String[] listContent ={"Account Setup","Fragment Two",
"Fragment Three","Main Page"};
final String[] fragments ={
"com.strawberryapps.accountsetup.AccountSetup",
"com.strawberryapps.backupnotes.BackupNotes",
"com.strawberryapps.notes.AddNote",
"com.strawberryapps.myapp.MainPage"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayAdapter<String> ad = new ArrayAdapter<String> (getActionBar().getThemedContext(), android.R.layout.simple_list_item_1, listContent);
final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);
final ListView list = (ListView) findViewById(R.id.drawer);
list.setAdapter(ad);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
drawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener(){
@Override
public void onDrawerClosed(View drawerView){
super.onDrawerClosed(drawerView);
android.support.v4.app.FragmentTransaction transition = getSupportFragmentManager().beginTransaction();
transition.replace(R.id.main, Fragment.instantiate(MainActivity.this, fragments[position]));
transition.commit();
}
});
}
});
}
Here is my activity_main.xml 这是我的activity_main.xml
<android.support.v4.widget.DrawerLayout

Kindly change color of background of fragment's layout .xml file.... Use this code in fragment's layout file in parent layout 请更改片段的布局.xml文件的背景颜色。...在父布局的片段的布局文件中使用此代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
