锁定手机屏幕后，活动再次开始

Question

我有下一个问题。 我正在开发游戏。 当我从物理按钮锁定设备并解锁时，游戏会再次开始。 活动再次开始。 解锁后，我想从锁定那一刻起继续播放。

Answer 1

然后，您需要将状态保存在onPause中，然后在onResume中再次加载

Answer 2

您需要使用onSaveInstanceState和onRestoreInstanceState 保存和恢复活动状态

救：

 static final String STATE_SCORE = "playerScore"; static final String STATE_LEVEL = "playerLevel"; ... @Override public void onSaveInstanceState(Bundle savedInstanceState) { // Save the user's current game state savedInstanceState.putInt(STATE_SCORE, mCurrentScore); savedInstanceState.putInt(STATE_LEVEL, mCurrentLevel); // Always call the superclass so it can save the view hierarchy state super.onSaveInstanceState(savedInstanceState); } 

恢复：

 public void onRestoreInstanceState(Bundle savedInstanceState) { // Always call the superclass so it can restore the view hierarchy super.onRestoreInstanceState(savedInstanceState); // Restore state members from saved instance mCurrentScore = savedInstanceState.getInt(STATE_SCORE); mCurrentLevel = savedInstanceState.getInt(STATE_LEVEL); }
