我试图在活动暂停之前通过使用以下代码覆盖onPause方法来显示toast消息:

@Override
protected void onPause() {
    Toast.makeText(this, "Paused", Toast.LENGTH_LONG);
    super.onPause();
}

根据此http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle 在返回此方法之前,不会暂停活动:

"Implementations of this method must be very quick because the next activity will not be resumed until this method returns."

但是根本不显示Toast消息。

答案 0 :(得分:9)

变化: Toast.makeText(this, "Paused", Toast.LENGTH_LONG)

为:

Toast.makeText(this, "Paused", Toast.LENGTH_LONG).show()
