Normaly, button Menu if press will
look like this.
We want Menu button can show some
tabs to choose an action, like to open new class.
In file string of tag values, add
these lines.
<string
name="he">Update</string>
<string name="he2">Newgame</string>
<string name="he3">Quit</string>
Change file main.xml in tag menu
like this.
<item
android:id="@+id/action_settings"
android:orderInCategory="1"
android:title="@string/action_settings"
app:showAsAction="ifRoom"
android:icon="@android:drawable/btn_star"/>
<item
android:id="@+id/new_game"
android:orderInCategory="2"
android:title="@string/he"
app:showAsAction="ifRoom"
android:icon="@android:drawable/btn_star"/>
<item
android:id="@+id/new_game2"
android:orderInCategory="3"
android:title="@string/he2"
app:showAsAction="ifRoom"
android:icon="@android:drawable/btn_star"/>
In main class, add this.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds
items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
startActivityForResult(new Intent(
android.provider.Settings.ACTION_SETTINGS), 0);
return true;
}
if (id == R.id.new_game) {
Intent
intent = new Intent(getApplicationContext(),
Newclass.class);
startActivity(intent);
return true;
}
if (id == R.id.new_game2) {
Intent
intent = new Intent(getApplicationContext(),
Newclass2.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
Now when press button Menu, screen
will look like this.
