我要求ACCESS_COARSE_LOCATION
權限,但沒有顯示對話框。請求授予權限時,不會顯示requestpermission對話框
這裏是我的代碼:
if (!checkPermissions()) {
requestPermissions();
} else {
getLastLocation();
}
這裏的requestPermission()
:
private void requestPermissions() {
boolean shouldProvideRationale =
ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.ACCESS_COARSE_LOCATION);
// Provide an additional rationale to the user. This would happen if the user denied the
// request previously, but didn't check the "Don't ask again" checkbox.
if (shouldProvideRationale) {
Log.i(TAG, "Displaying permission rationale to provide additional context.");
AlertDialog.Builder builder1 = new AlertDialog.Builder(MainActivity.this);
builder1.setMessage("Location permission is needed in order to show your current location");
builder1.setCancelable(true);
builder1.setPositiveButton(
"OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.RECORD_AUDIO},
PERMISSION_REQUEST_RECORD_AUDIO);
}
});
AlertDialog alert11 = builder1.create();
alert11.show();
} else {
Log.i(TAG, "Requesting permission");
// Request permission. It's possible this can be auto answered if device policy
// sets the permission in a given state or the user denied the permission
// previously and checked "Never ask again".
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
REQUEST_PERMISSIONS_REQUEST_CODE);
}
}
我得到08-31 13:02:25.067 8231-8231/com.appName.app/com.appName.app.MainActivity: Requesting permission
打印出來,但沒有對話框詢問許可顯示出來。
這是怎麼發生的?
