显示警报 requestPermissions 关闭时出现问题 Activity

Question

该程序的问题在于它在显示 权限警报 时 关闭了 Activity。

如果它应该以这种方式在程序中显示所需的警报

Build.gradle

android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.sgpco.mygiti"

    vectorDrawables.useSupportLibrary = true
}
signingConfigs {
    config {
        keyAlias '****'
        keyPassword '****'
        storeFile file('*****')
        storePassword '****'
    }
}
buildTypes {
    release {

            onRequestPermissionsResult(PERMISSION_REQUEST_CODE, REQUIRED_SDK_PERMISSIONS,

    }

@Override

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (Build.VERSION.SDK_INT >= 23) {
        switch (requestCode) {
            case PERMISSION_REQUEST_CODE:
                for (int index = permissions.length - 1; index >= 0; --index) {
                if (grantResults[index] != PackageManager.PERMISSION_GRANTED) {
                    finish();
                    return;
                }
            }
                break;
        }
    }
}
}

我所做的工作是根据上述方法进行的，我的一般问题是它在显示此警报时关闭Activity。

Answer 1

所以这是一些模拟代码来显示您的问题来源：

   Intent intent = new Intent(Splash_Activity.this, 
   Test_Activity.class);
   intent .addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
   intent .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   startActivity(intent);

正如你在此处看到的，当我启动 Test_Activity 时，我正在请求其中的权限 Activity，我在启动它的意图中添加了一些标志，以便当这个activity 不再可见，它会自动销毁，似乎请求权限确实阻止了 activity，就好像它不再可见一样，所以它被销毁，然后在权限后面有停电dialog 因为没有 activity alive 然后按下 deny 或 allow 将简单地关闭对话框并向 onRequestPermissionsResult 方法发送回调，但 activity 不活跃以接收回调。所以最初添加到意图的标志是问题所在。因此，请删除添加到启动 activity 请求权限的意图中的标志。
