Toast 직접 만들어 표시하기.

1. 구현해야 할 것

: 버튼을 누를 시, 아래의 노랑 테두리 박스가 나타면서 "모양 바꾼 토스트" 출력하기

 

 

 

 

 

2. MainActivity.java

import androidx.appcompat.app.AppCompatActivity;

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

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        LayoutInflater layoutInflater = getLayoutInflater();

        View layout = layoutInflater.inflate(
                R.layout.toastboarder,
                (ViewGroup) findViewById(R.id.toast_layout)
        );
        
        TextView tv1 = layout.findViewById(R.id.tv1);
        Toast toast = new Toast(this);
        tv1.setText("모양 바꾼 토스트");
        toast.setGravity(Gravity.CENTER, 0, -100);
        toast.setDuration(Toast.LENGTH_SHORT);
        toast.setView(layout);

        Button btn = findViewById(R.id.button);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                toast.show();
            }
        });

    }
}
