Android动态权限申请

Posted 2020-10-17 程小白

android系统中，目前Dangerous级别的权限都需要动态申请。步骤如下；

1、AndroidManfiest.xml中申明需要的动态权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.plbear.yyj.dangerouspermission">
    <!-- 声明权限 -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> 
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

2、代码中检查权限、申请权限

如下方法执行之后，会弹出提示框，提示要申请该权限

    fun onClick_requestPermission(v: View) {
        if (ContextCompat.checkSelfPermission(applicationContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), 0);
        }
    }

---

3、获取结果

1     override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
2         var i = 0;
3         while (i < permissions.size) {
4             Log.e(TAG, "permission:" + permissions[i] + " grantResult:" + grantResults[i])
5             i++
6         }
7         super.onRequestPermissionsResult(requestCode, permissions, grantResults)
8     }
