使用onSaveInstanceState保存TextView

Question

我试了几个小时来保存&恢复TextView和按钮。看来我无法保存TextView，因为“outState”需要一个字符串。

我犯了一个井字游戏，但我想保存所有的东西时，方向是“风景”

这里是我想要做的一个部分：

private Button lesBoutons[]; 
private Button rejouer; 
private Jeu jeu; 
private TextView leTexte; 
private int[] tabGagne; 
public boolean fini; 

@Override 
public void onSaveInstanceState(Bundle outState) { 
    super.onSaveInstanceState(outState); 
    outState.PutString("savText", leTexte); 
    //TextView savTexte = leTexte; 
    //String phrase=leTexte.toString(); 
    //outState.putString("TEST", phrase); 
    //leTexte.getResources(); 
} 

@Override 
protected void onRestoreInstanceState(Bundle savedInstanceState) { 
super.onRestoreInstanceState(savedInstanceState); 
// leTexte.setText(savedInstanceState.getString("TEST")); 
} 

我怎么能保存这个TextViews和所有的按钮？

Answer 1

做一个leTexte.getText()。这会让你看到文本，但要确保你先初始化TextView对象。

Answer 2

Android在调用您的活动之前先调用onSaveInstanceState()，以便保存有关应用程序状态的数据。然后您可以在onCreate()或onRestoreInstanceState()期间恢复状态。

@Override 
public void onSaveInstanceState(Bundle outState) { 
super.onSaveInstanceState(outState); 
outState.putString("savText", leTexte.getText().toString()); 
//save the state 
//1st parameter is the key 
//2nd parameter is the value 
} 

@Override 
protected void onRestoreInstanceState(Bundle savedInstanceState) { 
super.onRestoreInstanceState(savedInstanceState); 
leTexte.setText(savedInstanceState.getString("savText")); 
//restore it using the key 
}
