Android動態權限申請

Android系統中，目前Dangerous級別的權限都需要動態申請。步驟如下；

---

1、AndroidManfiest.xml中申明需要的動態權限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.plbear.yyj.dangerouspermission">
    <!-- 聲明權限 -->
    <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、代碼中檢查權限、申請權限

如下方法執行之后，會彈出提示框，提示要申請該權限

    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、獲取結果

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