Java 旋转屏幕时onSaveInstanceState（）不工作

可能，我的代码是正确的，但是当屏幕旋转时，方法onSaveInstanceState（）不起作用。活动销毁（onDestroy（）工作）后，数据不会保存。但是，该方法在方法onPause（）和onStop（）之后工作。activity上有一个元素-textView，我在使用这些方法时编写文本。有错误吗？先谢谢你

    public class MainActivity extends AppCompatActivity {

    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getSupportActionBar().hide();
        textView = findViewById(R.id.textView);

        if (savedInstanceState != null)
        {
           textView.setText(savedInstanceState.getString("saveInstance"));
        }

        Log.i("lifecycle show", "onCreate() worked");
        textView.append("onCreate() worked\n");
    }

    @Override
    protected void onStart() {
        super.onStart();
        Log.i("lifecycle show", "onStart() worked");
        textView.append("onStart() worked\n");
    }

    @Override
    protected void onResume() {
        super.onResume();
        Log.i("lifecycle show", "onResume() worked");
        textView.append("onResume() worked\n");
    }

    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i("lifecycle show", "onRestart() worked");
        textView.append("onRestart() worked\n");
    }

    @Override
    protected void onPause() {
        super.onPause();
        Log.i("lifecycle show", "onPause() worked");
        textView.append("onPause() worked\n");
    }

    @Override
    protected void onStop() {
        super.onStop();
        Log.i("lifecycle show", "onStop() worked");
        textView.append("onStop() worked\n");
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        Log.i("lifecycle show", "onDestroy() worked");
        textView.append("onDestroy() worked\n");
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Log.i("lifecycle show", "onSaveInstanceState() worked");
        textView.append("onSaveInstanceState() worked\n");
        outState.putString("savedInstance", textView.getText().toString());
    }
}

标签错了。您使用“savedInstance”作为标记放置字符串，然后逐个标记“saveInstance”获取字符串。

我的上帝。。。非常感谢你。这很有趣，但我很惭愧
