Android棉花糖上的运行时权限

问题描述：

我想知道运行时权限弹出窗口在活动中是否可见. 我怎么知道?是否有任何相同的回调或重写方法.

I would like to know whether the runtime permission popup is visible or not in the activity. How can i know that? Is there any callback or overrided method for the same.

答

您可以自行请求权限，以便知道其显示时间.您还可以添加结果回调.参见下面的代码；

You request permissions yourself so you know when it is shown. You can also add a result callback. See the code below;

public void requestPermissions(List<String> permissions, ActivityCompat.OnRequestPermissionsResultCallback onRequestPermissionsResultCallback) {
    String[] params = permissions.toArray(new String[permissions.size()]);
    requestPermissions(params, onRequestPermissionsResultCallback);
}

public void requestPermissions(String[] permissions, ActivityCompat.OnRequestPermissionsResultCallback onRequestPermissionsResultCallback) {
    this.onRequestPermissionsResultCallback = onRequestPermissionsResultCallback;
    ActivityCompat.requestPermissions(this, permissions, REQUEST_CODE_PERMISSIONS);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == REQUEST_CODE_PERMISSIONS && onRequestPermissionsResultCallback != null) {
        this.onRequestPermissionsResultCallback.onRequestPermissionsResult(requestCode, permissions, grantResults);
        this.onRequestPermissionsResultCallback = null;
    }
}

这通常位于某种基础Activity类中.

This would generally sit inside some kind of base Activity class.
