以開啟麥克風權限為例

1.在AndroidManifest.xml中加上

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

2.在AppActivity.java文件的protected voidonCreate(Bundle savedInstanceState) {}方法里可加入以下代碼：

PackageManager pkgManager= getPackageManager();

boolean audioSatePermission =

pkgManager.checkPermission(Manifest.permission.RECORD_AUDIO, getPackageName()) == PackageManager.PERMISSION_GRANTED;

if(Build.VERSION.SDK_INT>=23&&!audioSatePermission) {

requestPermission();

}

3.requestPermission();方法的具體寫法:

private void requestPermission() {

ActivityCompat.requestPermissions(this,newString[] {Manifest.permission.RECORD_AUDIO},

REQUEST_PERMISSION);

}
