当我试图在图像上显示时,在我的应用程序中,我有一个地址栏,下拉操作菜单和一个webview。
我的问题是;我如何添加描述的网页链接,点击时链接到webview? 菜单不可更改或可添加。
谢谢。

请检查源代码,我认为它对您有所帮助。这里ActionBar.OnNavigationListener Click Event
public class MainActivity extends Activity {
/** An array of strings to populate dropdown list */
String[] actions = new String[] {
"Bookmark",
"Subscribe",
"Share"
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/** Create an array adapter to populate dropdownlist */
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_spinner_dropdown_item, actions);
/** Enabling dropdown list navigation for the action bar */
getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
/** Defining Navigation listener */
ActionBar.OnNavigationListener navigationListener = new OnNavigationListener() {
@Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
Toast.makeText(getBaseContext(), "You selected : " + actions[itemPosition] , Toast.LENGTH_SHORT).show();
return false;
}
};
/** Setting dropdown items and item navigation listener for the actionbar */
getActionBar().setListNavigationCallbacks(adapter, navigationListener);
}
}
