对应的效果图

 不需要交任何 依赖  

下面 来看看布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.newstablayout.MainActivity">


    <Button
        android:text="点击"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button3" />
</LinearLayout>

下面就是 对应的Mainactiviy

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

  /*  private Intent intent;*/
    Button button3;
    private TimeCount time;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    /*    findViewById(R.id.button).setOnClickListener(this);
        findViewById(R.id.button2).setOnClickListener(this);*/
        button3 = (Button)findViewById(R.id.button3);
        time = new TimeCount(60000, 1000);

        button3.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                time.start();
            }
        });

    }

  /*  @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button:
                intent=new Intent(MainActivity.this, TabLessActivity.class);
                break;
            case R.id.button2:
                intent=new Intent(MainActivity.this, TabManyActivity.class);
                break;
        }
        startActivity(intent);
    }*/
    class TimeCount extends CountDownTimer {

        public TimeCount(long millisInFuture, long countDownInterval) {
            super(millisInFuture, countDownInterval);
        }

        @Override
        public void onTick(long millisUntilFinished) {
            button3.setBackgroundColor(Color.parseColor("#B6B6D8"));
            button3.setClickable(false);
            button3.setText("("+millisUntilFinished / 1000 +") ");
        }

        @Override
        public void onFinish() {
            button3.setText("重新获取验证码");
            button3.setClickable(true);
            button3.setBackgroundColor(Color.parseColor("#4EB84A"));

        }
    }
}
