Android Study Notes: Implementation Sidebar of DrawerLayout,

Layout file required by DrawerLayout

First, use android. support. v4.widget. DrawerLayout as the tag.

In addition, you need to set the android: layout_gravity = "start" start of the sidebar layout to the left layout and end to the right layout.

 

 

Code in the activity:

Private DrawerLayout mDrawerLayout;
Private ActionBarDrawerToggle mActionBarDrawerToggle;

// The android. support. v7.app. ActionBarDrawerToggle package should be used in ActionBarDrawerToggle. If not, please inport V7 Database support/v7/appcompat

// Obtain the sidebar id.

MDrawerLayout = (DrawerLayout) findViewById (R. id. f1 );

MActionBarDrawerToggle = new ActionBarDrawerToggle (this, mDrawerLayout,
R. string. open, R. string. close );

// Listen to mDrawerLayout.

MDrawerLayout. setDrawerListener (new DrawerListener (){

@ Override
Public void onDrawerStateChanged (int arg0 ){
MActionBarDrawerToggle. onDrawerStateChanged (arg0 );
}

@ Override
Public void onDrawerSlide (View arg0, float arg1 ){
MActionBarDrawerToggle. onDrawerSlide (arg0, arg1 );
}

@ Override
Public void onDrawerOpened (View arg0 ){
MActionBarDrawerToggle. onDrawerOpened (arg0 );
}

@ Override
Public void onDrawerClosed (View arg0 ){
MActionBarDrawerToggle. onDrawerClosed (arg0 );
}
});

Note: Another simple listening method

MDrawerLayout. setDrawerListener (mActionBarDrawerToggle );

@ Override
Protected void onPostCreate (Bundle savedInstanceState ){
// TODO Auto-generated method stub
Super. onPostCreate (savedInstanceState );
MActionBarDrawerToggle. syncState ();
}

Public boolean onOptionsItemSelected (MenuItem item ){

Return mActionBarDrawerToggle. onOptionsItemSelected (item)
| Super. onOptionsItemSelected (item );
}
