如何找回我在转到另一个活动后离开的位置，ListView？

private int savedPosition = -1;

@Override
protected void onPause() {
    super.onPause();
    ListView listView = findViewById(R.id.listView);
    savedPosition = listView.getFirstVisiblePosition();
}

@Override
protected void onResume() {
    super.onResume();
    ListView listView = findViewById(R.id.listView);
    if (savedPosition != -1) {
        listView.setSelection(savedPosition);
    }
}

<activity
    android:name=".YourActivity"
    android:configChanges="orientation|screenSize">
</activity>

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    ListView listView = findViewById(R.id.listView);
    outState.putInt("saved_position", listView.getFirstVisiblePosition());
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    savedPosition = savedInstanceState.getInt("saved_position");
}
