如何将闪烁的文本视图显示5秒，然后使其不可见？

import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    private TextView textView;
    private Handler handler;
    private boolean isVisible = true;

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

        textView = findViewById(R.id.textView);
        handler = new Handler();

        // 开始闪烁
        startBlinking();
    }

    private void startBlinking() {
        // 设置初始文本内容
        textView.setText("闪烁的文本");

        // 定义定时器或者Handler的延迟时间为5秒
        long delayMillis = 5000;

        // 定义定时器或者Handler的回调函数
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                // 切换文本视图的可见性
                if (isVisible) {
                    textView.setVisibility(View.INVISIBLE);
                    isVisible = false;
                } else {
                    textView.setVisibility(View.VISIBLE);
                    isVisible = true;
                }

                // 继续闪烁
                handler.postDelayed(this, delayMillis);
            }
        };

        // 开始闪烁
        handler.postDelayed(runnable, delayMillis);
    }
}
