索尼 xperia 的 onActivityResult 问题

Question

i start activity for result to open GPS 然后收到 OnACtivityResult .. 它在某些手机上工作正常，但索尼不工作，我不知道为什么我使用嵌套片段开始 activity

Intent callGPSSettingIntent = new Intent(
                                        android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                                startActivityForResult(
                                        callGPSSettingIntent, openGPSRequest);

然后在片段中接收

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == openGPSRequest) {
            try {
                activity.hideProgress();
            } catch (Exception e) {

            }
            activity.replaceCurrentFragment(
                    FramentNavigationMapInside.getInstance(branche), true, true);
        }
    }

主要activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);



    }

并在每个片段中覆盖 onActivityResult

我在 lenove 和 samsung 上测试它并且工作正常，但是在 sony xperia 上不工作，只有 onActivityResult 主要 activity 调用

Answer 1

通过

解决我的问题

我们在 Fragment 的世界中经常遇到的一个常见问题是：虽然我们可以直接从 Nested Fragment 调用 startActivityForResult 但似乎永远不会调用 onActivityResult这给处理 Activity 嵌套片段的结果带来了很多麻烦。

解决方法

所以我们将从现在开始从 Fragment 调用 getActivity().startActivityForResult(...) 而不是仅仅调用 startActivityResult(...) .像这样：

// In Fragment
Intent intent = new Intent(getActivity(), SecondActivity.class);
getActivity().startActivityForResult(intent, 12345);

因此，所有接收到的结果都将在一个地方处理：ActivityFragment 所在 Activity 的结果。

问题是如何将Activity结果发送到Fragment？由于我们无法以正常方式或至少以简单方式直接与所有嵌套片段通信。另一个事实是，每个片段都知道它必须处理哪个 requestCode，因为它也是调用 startActivityForResult 的那个。所以我们选择"broadcast to every single Fragment that is active at time. And let those Fragments check requestCode and do what they want."

的方式

谈到广播，LocalBroadcastManager 可以胜任这项工作，但机制太老了。我选择了另一种选择，即 EventBus，它有很多选择。我选择的是来自广场的奥托。它在性能和健壮性方面真的很出色。

dependencies {
  compile 'com.squareup:otto:1.3.6'
}

以 Otto 的方式，让我们创建一个总线事件作为一个包，其中包含那些 Activity 结果值。

import android.content.Intent;

/**
 * Created by nuuneoi on 3/12/2015.
 */
public class ActivityResultEvent {

    private int requestCode;
    private int resultCode;
    private Intent data;

    public ActivityResultEvent(int requestCode, int resultCode, Intent data) {
        this.requestCode = requestCode;
        this.resultCode = resultCode;
        this.data = data;
    }

    public int getRequestCode() {
        return requestCode;
    }

    public void setRequestCode(int requestCode) {
        this.requestCode = requestCode;
    }

    public int getResultCode() {
        return resultCode;
    }

    public void setResultCode(int resultCode) {
        this.resultCode = resultCode;
    }

    public Intent getData() {
        return data;
    }

    public void setData(Intent data) {
        this.data = data;
    }
}

import android.os.Handler;
import android.os.Looper;

import com.squareup.otto.Bus;

/**
 * Created by nuuneoi on 3/12/2015.
 */
public class ActivityResultBus extends Bus {

    private static ActivityResultBus instance;

    public static ActivityResultBus getInstance() {
        if (instance == null)
            instance = new ActivityResultBus();
        return instance;
    }

    private Handler mHandler = new Handler(Looper.getMainLooper());

    public void postQueue(final Object obj) {
        mHandler.post(new Runnable() {
            @Override
            public void run() {
                ActivityResultBus.getInstance().post(obj);
            }
        });
    }

}

并且在activity

public class MainActivity extends ActionBarActivity {

    ...

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        ActivityResultBus.getInstance().postQueue(
                    new ActivityResultEvent(requestCode, resultCode, data));
    }

    ...

}

并最终在Activity片段

中处理返回数据

public class BodyFragment extends Fragment {

    ...

    @Override
    public void onStart() {
        super.onStart();
        ActivityResultBus.getInstance().register(mActivityResultSubscriber);
    }

    @Override
    public void onStop() {
        super.onStop();
        ActivityResultBus.getInstance().unregister(mActivityResultSubscriber);
    }

    private Object mActivityResultSubscriber = new Object() {
        @Subscribe
        public void onActivityResultReceived(ActivityResultEvent event) {
            int requestCode = event.getRequestCode();
            int resultCode = event.getResultCode();
            Intent data = event.getData();
            onActivityResult(requestCode, resultCode, data);
        }
    };
 @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        // Don't forget to check requestCode before continuing your job
        if (requestCode == 12345) {
            // Do your job
            tvResult.setText("Result Code = " + resultCode);
        }
    }
    ...

}
