嗨，朋友们，当按下android键盘上的默认菜单按钮时，我想从屏幕底部弹出一个按钮。我想从弹出按钮导航到其他屏幕。
You first have to declare your desired menu in /menu/menu.xml then you need a inflater for your menu:
// menuinflater
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
要处理您的菜单：
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// only one menu option here for preferences
// for more just add new case with your ids
case R.id.firstmenuitem:
// Launch preferences activity
Intent i = new Intent(youractivity.this, preferences.class);
startActivity(i);
break;
}
return true;
}
