引导页之页面等待3秒跳转

效果图：

页面布局：

二：activity的编写，用到时间空间戳

package com.example.administrator.myapplication;

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

/**  跳转时间倒计时页面
 * Created by Administrator on 2016/12/23.
 */

public class JumpActivity extends Activity {
    TextView textView;
    int time=3;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.jump);
        textView= (TextView) findViewById(R.id.textview);

        handler.postDelayed(runnable,3000);

    }
    Handler handler=new Handler();
    Runnable runnable=new Runnable() {
        @Override
        public void run() {
            time--;
            handler.postDelayed(this,2000);
            textView.setText("跳转："+time+"秒");

            if(time==0){
                Intent intent=new Intent(JumpActivity.this,TestActivity.class);
                startActivity(intent);
                finish();
            }else {
                textView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent=new Intent(JumpActivity.this,TestActivity.class);
                        startActivity(intent);
                        //结束线程
                        handler.removeCallbacks(runnable);
                        finish();
                    }
                });
            }
        }
    };
}
