在 3.0 蜂窝版之前，这是对 Android 的弃用答案，请使用 SolArabehety 的回答或查看这个线程.

Edited

It is a deprecated answer to Android before version 3.0 honeycomb, please uses SolArabehety's answer or look at this thread.

我保留这个答案的唯一原因是android 3.0之前Android动画有很多问题的历史原因，这个糟糕"解决方案在当时有效，现在使用它是不可想象的，所以只是去寻找动画解决方案，不要使用此代码.

The only reason I keep this answer is to historical reasons before android 3.0 Android animations had a lot of problems, this "bad" solution work at that time, nowadays it is unthinkable to use it, so just go for an animation solution, don't use this code.

package teste.blink;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.TextView;

public class TesteBlinkActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        blink();
}

private void blink(){
    final Handler handler = new Handler();
    new Thread(new Runnable() {
        @Override
        public void run() {
        int timeToBlink = 1000;    //in milissegunds
        try{Thread.sleep(timeToBlink);}catch (Exception e) {}
            handler.post(new Runnable() {
                @Override
                    public void run() {
                    TextView txt = (TextView) findViewById(R.id.usage);
                    if(txt.getVisibility() == View.VISIBLE){
                        txt.setVisibility(View.INVISIBLE);
                    }else{
                        txt.setVisibility(View.VISIBLE);
                    }
                    blink();
                }
                });
            }
        }).start();
    }

<TextView
   android:id="@+id/usage"
   android:layout_marginTop="220dip"
   android:layout_marginLeft="45dip"
   android:layout_marginRight="15dip"
   android:typeface="serif"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Google "
   android:textColor="#030900"/>
