安卓: Button onClick在3秒后做出反应

// 布局文件中定义Button
<Button
    android:id="@+id/myButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click Me"
    android:onClick="onButtonClick" />

// Activity或Fragment中的代码
public class MyActivity extends AppCompatActivity {
    private Button myButton;

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

        myButton = findViewById(R.id.myButton);
    }

    public void onButtonClick(View view) {
        // 延迟3秒钟
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        // 在延迟结束后执行操作
        Toast.makeText(this, "Button clicked after 3 seconds", Toast.LENGTH_SHORT).show();
    }
}
