/* 这里涉及到一个API，ContextCompat.checkSelfPermission，主要用于检测某个权限是否已经被授予，
方法返回值为PackageManager.PERMISSION_DENIED或者PackageManager.PERMISSION_GRANTED。
当返回DENIED就需要进行申请授权了。*/
/* 申请授权
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
该方法是异步的，第一个参数是Context；第二个参数是需要申请的权限的字符串数组；
第三个参数为requestCode，主要用于回调的时候检测。可以从方法名requestPermissions以及第二个参数看出，
是支持一次性申请多个权限的，系统会通过对话框逐一询问用户是否授权。*/
if(ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PermissionChecker.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},RQUESTCODE);
}
}

/* 处理权限申请回调*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if(requestCode==RQUESTCODE){
if(grantResults[0]==PermissionChecker.PERMISSION_GRANTED){
//权限申请授权成功
}
}

}
