android 棉花糖权限
android marshmallow permission
如何在下面的代码中得到 MY_PERMISSIONS_REQUEST_READ_PHONE_STATE?我没看到。我在 dev.android.com 中搜索但没有找到任何内容。
private void checkPermission() {
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_PHONE_STATE)) {
// Show an expanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
// MY_PERMISSIONS_REQUEST_READ_PHONE_STATE is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
正如您在评论中看到的那样,这是一个应用程序定义的 int 常量,因此只需这样定义即可:
// Add this definition:
public static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 999;
private void checkPermission() {
//.....
}
然后,使用它onRequestPermissionsResult()
:
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// read-phone-state-related task you need to do.
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
Toast.makeText(this, "permission denied", Toast.LENGTH_LONG).show();
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
