Question

在MyApplication启动应用程序时，如果用户未登录，我将使用标记FLAG_ACTIVITY_NEW_TASK开始登录活动。在onCreate()内的此登录活动中，我正在请求位置权限。权限对话框显示但在用户有机会执行任何操作之前会自动被解除。为什么会这样？我在onCreate方法的第一行请求这样的许可：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && (ActivityCompat.checkSelfPermission(mActivity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ||
                ActivityCompat.checkSelfPermission(mActivity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                mActivity.requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
                        REQUEST_LOCATION_ACCESS_CODE);
            }

Answer 1

确保已包含

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

你的清单中的

在你的onCreate（）中检查是否允许权限

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_home);

  if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&!isPermissionAllowed()){
   ActivityCompat.requestPermissions(Home.this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
                    MY_PERMISSIONS_REQUEST_LOCATION);

   }else{
  //continue execution
  }
}

private boolean isPermissionAllowed(){
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && 
ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
)!=PackageManager.PERMISSION_GRANTED){
        return false;
    }
    return true;
}

请求权限对话框立即消失
