Android 6.0 – 申请动态权限

• 本文只申请读写权限，举一反三，按照这个模版也可以申请其他权限。

AndroidManifest.xml ↓

<!--加读写权限--><uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\"/><uses-permission android:name=\"android.permission.READ_EXTERNAL_STORAGE\"/>

Java ↓

//定义请求码private static final int REQUEST_EXTERNAL_STORAGE = 1;private static String[] PERMISSIONS = {\"android.permission.READ_EXTERNAL_STORAGE\",\"android.permission.WRITE_EXTERNAL_STORAGE\" };//然后通过一个函数来申请public static void readWritePermission(Activity activity) {try {//检测是否有权限：permission = 0 ，则有权限int permission = ActivityCompat.checkSelfPermission(activity,\"android.permission.WRITE_EXTERNAL_STORAGE\");//判断是否有权限，没有则弹出对话框if (permission != PackageManager.PERMISSION_GRANTED) {//Activity的实例、String数组、请求码ActivityCompat.requestPermissions(activity, PERMISSIONS,REQUEST_EXTERNAL_STORAGE);}} catch (Exception e) {e.printStackTrace();}}//--------------在 onCreate中调用此函数--------------readWritePermission(this);
