我怎样才能在Android中解决此错误？ (完成非零值)

我的代码很长,我发布了所有的R.在我加入之后突出显示了红色

LayoutInflater inflater = getLayoutInflater();
            View layout = inflater.inflate(R.layout.toast_layout,(ViewGroup) findViewById(R.id.toast_layout_root));

            TextView text = (TextView) layout.findViewById(R.id.text);
            text.setText("Please SELEct a Level!");
            text.setTextColor(Color.bLUE);
            text.setTextSize(15);

            Toast toast = new Toast(getApplicationContext());
            toast.setGravity(Gravity.CENTER,0);
            toast.setDuration(Toast.LENGTH_SHORT);
            // toast.getView().setBACkgroundColor(Color.bLUE);
            toast.setView(layout);
            toast.show();

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://scheR_253_11845@as.android.com/apk/res/android"
    android:id="@+id/toast_layout_root"

    <ImageView android:src="@drawable/droid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="8dp"
        />

    <TextView android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

</LinearLayout>
