如何在android中创建具有相同大小按钮的键盘

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <Button
        android:id="@+id/button1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button 1" />

    <Button
        android:id="@+id/button2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button 2" />

    <!-- 添加更多按钮... -->

</LinearLayout>

public class KeyboardActivity extends AppCompatActivity {

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

        Button button1 = findViewById(R.id.button1);
        Button button2 = findViewById(R.id.button2);

        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 执行按钮1的操作
                Toast.makeText(KeyboardActivity.this, "Button 1 clicked", Toast.LENGTH_SHORT).show();
            }
        });

        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 执行按钮2的操作
                Toast.makeText(KeyboardActivity.this, "Button 2 clicked", Toast.LENGTH_SHORT).show();
            }
        });

        // 添加更多按钮的点击事件监听器...
    }
}
