Question

我有一个带有ImageView的片段。当用户单击此图像时，我想请求本地化的权限，但尽管＆＃34; requestPermission（）＆＃34;执行后，请求对话框未显示。

我的片段onCreateView方法

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                            Bundle savedInstanceState) {

    View center = inflater.inflate(R.layout.board, container, false);
    position = (ImageView) center.findViewById(R.id.position);

    position.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

                if (ContextCompat.checkSelfPermission(getActivity(),
                        Manifest.permission.ACCESS_FINE_LOCATION)
                        != PackageManager.PERMISSION_GRANTED) {

                    if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
                            Manifest.permission.ACCESS_FINE_LOCATION)) {

                        Toast.makeText(getContext(),
                                "I need the permission pls",
                                Toast.LENGTH_LONG).show();
                    }

                    requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION,}, LOCALIZATION_PERMISSION);

                }
            }
        }
    });
    return center;
}

注意:: shouldShowRequestPermissionRationale永远不会成立。我用调试器验证了这一点。

我在Manifest中也获得了许可

<?xml version="1.0" encoding="utf-8"?>

    <manifest
        xmlns:android="http://schemas.android.com/apk/res/android"
        package="it.peoople">

    <uses-permissions android:name="android.permissions.INTERNET" />
    <uses-permissions android:name="android.permissions.READ_EXTERNAL_STORAGE"/>
    <uses-permissions android:name="android.permissions.WRITE_EXTERNAL_STORAGE" />
    <uses-permissions android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permissions android:name="android.permission.ACCESS_COARSE_LOCATION"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name="it.peoople.main.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="stateHidden|adjustPan" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name="it.peoople.floating.Messaging"
            android:screenOrientation="portrait">
        </activity>

        <activity android:name="it.peoople.floating.Registration"
            android:screenOrientation="portrait">
        </activity>
    </application>

</manifest>

注意::权限对话框从未出现，所以我从不检查“不要再问”＃34;。

每次执行请求权限都会被自动拒绝，Android logcat会打印此行

请帮帮我。

非常感谢。

Answer 1

我认为你应该将它移到活动中并实现一个新的监听器来从片段中与它进行交互。

你的问题是，你永远不会执行你刚刚建立它的toast，但是在它上面调用.show（）。

但是您要查找的对话框不是Android的内置功能，您需要自己构建它，如下所示：

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage(R.string.permission_prompt_location);
        builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                ActivityCompat.requestPermissions(
                        SwipeActivity.this,
                        new String[]{Manifest.permission.ACCESS_FINE_LOCATION,
                                Manifest.permission.ACCESS_COARSE_LOCATION},
                        REQUEST_LOCATION);
            }
        });
        builder.create().show();

Answer 2

使用boolean shouldShowRequestPermissionRationale (String permission)

而不是boolean shouldShowRequestPermissionRationale (Activity activity, String permission)。

Fragment中的requestPermission未显示对话框
