Please check the reason why the toast message from Android Studio doesn't pop up crying

Hello,

I'm Corinne, and I'm self-taught at Android Studio.

I set the gravity on the toast message as below, but the button pops up and the message doesn't pop upㅠ<

If you change AMD from Nexus 5 something to Pixel something, a toast message appears, but it doesn't show up with the set gravity ㅠ<

I don't know what the problem is Masters, please teach me ㅠ<

package org.techtown.toast;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast = Toast.makeText(getApplicationContext(), "Toast changed location", Toast.LENGTH_LONG);
                toast.setGravity(Gravity.TOP|Gravity.LEFT,200,200);
                toast.show();
            }
        });

     }
}

Toast#setGravity

If you check the setGravity document in the toast class, it says that it does not work for simple text toast while targeting version R or higher.

I think you can use the toast with a custom view.

Below is a snippet with a simple custom view.

// MainActivity.java
findViewById(R.id.main_button1).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "onClick: ");
                LayoutInflater inflater = getLayoutInflater();
                View layout = inflater.inflate(R.layout.custom_toast,
                        (ViewGroup) findViewById(R.id.custom_toast_container));

                TextView text = (TextView) layout.findViewById(R.id.text);
                text.setText("This is a custom toast");

                Toast toast = new Toast(getApplicationContext());
                toast.setGravity(Gravity.TOP|Gravity.LEFT,200,200);
                toast.setDuration(Toast.LENGTH_LONG);
                toast.setView(layout);
                toast.show();
            }
        });

<LinearLayout 
<!-- custom_toast.xml -->
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/custom_toast_container"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="8dp"
    android:background="#DAAA"
    >
    <TextView android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#FFF"
        android:text="TOAST"
        />
</LinearLayout>
