Answer 1

然后，你需要保存的onPause状态和的onResume

Answer 2

再次装入您使用onSaveInstanceState和onRestoreInstanceState

save:

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); 
} 

需要 save and restore state of your activity

restore:

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); 
}
