TabbarActivity 片段未调用到 onActivityResult

Question

我正在使用 tabbaractivity 并且其中一个选项卡包含 listView 我想在每次添加对象时更新 listView。 添加对象我从新 activity 我想要的是什么时候 activity 将关闭 listView 将通过使用更新 adapter.notifydatachanged

在我的 activity 中包含选项卡

   if (id == R.id.addButton) {
        Intent intent = new Intent(rootViewTabBarActivity.this, addPictureActivity.class);
        startActivityForResult(intent,101);
        return true;
    }

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

在片段中（选项卡之一）

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if ((requestCode == 101) && (resultCode == Activity.RESULT_OK))
        adapter.notifyDataSetChanged();
}

和创建对象并将其保存到数据库的activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAM_REQUEST) {
        Bitmap btmp = (Bitmap)data.getExtras().get("data");
        takenPhoto.setImageBitmap(btmp);
    }
}
@Override
protected void onDestroy() {
    super.onDestroy();
    setResult(Activity.RESULT_OK);
}

谢谢

fragment not called to onActivityResult

您错过了将数据从 Activity 传递到片段 在Activity中，你的代码应该是这样的：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
            YourFragment fragment = getFragment();
            if (fragment != null) {
                // Pass data to Fragment
                fragment.onActivityResult(requestCode, resultCode, data);
            }
        }

    }

public YourFragment getFragment() {
        // You can find your fragment (by tag/ by id) here depends on your layout
    }
