关于OnResume的问题

[Nabati]

在另一个activity之中选择选项，获取boolean值，返回mainactivity后调用onResume，在onResume中用获取的boolean判断应该变成那种功能（两个功能在一个acivity里写的 重力感应和非重力感应）但是发现在默认功能没有问题。 但是选择另一种模式的时候，两种功能的函数都被调用了，就还留在默认模式下，求解决！

主要代码如下：
public class MainActivity extends AppCompatActivity {
private TextView textView;
MyView mAnimView = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout root = (LinearLayout) findViewById(R.id.root);
final DrawView draw = new DrawView(this);
draw.setMinimumWidth(300);
draw.setMinimumHeight(500);
root.addView(draw);
}


@Override
public void onResume(){
SharedPreferences modle = getSharedPreferences("MODEL", Context.MODE_PRIVATE);
boolean x = modle.getBoolean("model",true);
Log.v("现在的boolean为："," "+x);
if(x==false){
LinearLayout root = (LinearLayout) findViewById(R.id.root);
Log.v("执行了1："," "+x);
final MyView mAnimView = new MyView(this);
root.addView(mAnimView);
}
else{

LinearLayout root = (LinearLayout) findViewById(R.id.root);
final DrawView draw = new DrawView(this);
draw.setMinimumWidth(300);
draw.setMinimumHeight(500);
root.addView(draw);
Log.v("执行了2"," "+x);
}
super.onResume();
}

求大神解决！

你确认你SharedPreferences 中存入值并提交了吗？参数key都对吗？

SharedPreferences 都存入了。打印都没有问题的

    public void onResume(){
        SharedPreferences modle = getSharedPreferences("MODEL", Context.MODE_PRIVATE);
        boolean x = modle.getBoolean("model",true);
        Log.v("现在的boolean为：","      "+x);
        if(!x) {
            LinearLayout root = (LinearLayout) findViewById(R.id.root);
            Log.v("执行了1：","      "+x);
            root.removeAllViews();
            mAnimView = new MyView(this);
            root.addView(mAnimView);
        }  else {
            LinearLayout root = (LinearLayout) findViewById(R.id.root);
            root.removeAllViews();
            final DrawView draw = new DrawView(this);
            draw.setMinimumWidth(300);
            draw.setMinimumHeight(500);
            root.addView(draw);
            Log.v("执行了2","      "+x);
        }
        super.onResume();
    }

改成這樣看看

运行完onResume好像还要回头再运行一遍onCreat，是不是这样啊？ 因为Log出模式1的文字两遍......
