I just can't find it. Thank you

Answer 1

The following codes will set the TextView score to blank when Button one is clicked

First approach

To use the android:onClick="score1" in your XML

Add this to your activity

TextView mTvScore1 = (TextView) findViewById(R.id.score)

public void score1(View v) {
    mTvScore1.setText("");
}

Second approach

Button mBtn = (Button) findViewById(R.id.one)
TextView mTvScore1 = (TextView) findViewById(R.id.score)

mBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mTvScore1.setText("");
    }
});

Activity code

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

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

        TextView mTvScore1 = (TextView) findViewById(R.id.score);
        Button mBtn = (Button) findViewById(R.id.one);

        mBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                score1(v);
            }
        });
    }

    public void score1(View v) {
        mTvScore1.setText("");
    }
}
