左边按钮是退出，右边是下一页，后面几张是左边箭头是跳到前一张,以前很纯真的用startAcitivty往前跳，跳到第一页的时候退出，后面的Activity还在。

就算launchermode改成singleTask也还是这样,还是要finish()才可以大道Back的效果。

ActivityB.java

package cn.com.bvin.stack;import android.app.Activity;import android.content.Intent;import android.graphics.Color;import android.os.Bundle;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.widget.Button;import android.widget.TextView;public class ActivityB extends Activity{    private ViewGroup rootContainer;    private Button btNext,btBack;    private TextView tvBomt,tvTop;    @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        getWindow().requestFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.main);        initViews();    }    public void initViews(){        rootContainer = (ViewGroup)findViewById(R.id.root);        rootContainer.setBackgroundResource(R.drawable.shake_bg3);        btNext = (Button)findViewById(R.id.btNext);        btBack = (Button)findViewById(R.id.btBack);        tvTop = (TextView)findViewById(R.id.tvTop);        tvTop.setTextColor(Color.BLACK);        tvTop.setText("Hello world,"+getClass().getName()+"!");        tvBomt = (TextView)findViewById(R.id.tvBottom);        tvBomt.setText("第三页");        tvBomt.setTextColor(Color.BLACK);        rootContainer.setBackgroundResource(R.drawable.shake_bg3);        btNext.setOnClickListener(new View.OnClickListener() {                        @Override            public void onClick(View v) {                // TODO Auto-generated method stub                startActivity(new Intent(ActivityB.this,ActivityC.class));            }        });        btBack.setOnClickListener(new View.OnClickListener() {                        @Override            public void onClick(View v) {                // TODO Auto-generated method stub                //startActivity(new Intent(ActivityB.this,AcitivtyA.class));                finish();            }        });    }}
