今天闲着没事敲了几个简单的框架

摘要: 有三种 一种是 viewpager 一种是 fragment 一种是 fragment+viewpager,　敲累了先休息下，还有很多附加功能没有添加上。以后会慢慢补上 下载地址：http://download.csdn.net/download/qq_33363534/9466845

MainActivity:

简单的三个button

public class MainActivity extends Activity implements View.OnClickListener {

Button btn_fragment_viewpager;
Button btn_fragment;
Button btn_viewpager;

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

initView();
initEvent();

}

/**
* 初始化事件
*/
private void initEvent() {
btn_viewpager.setOnClickListener(this);
btn_fragment.setOnClickListener(this);
btn_fragment_viewpager.setOnClickListener(this);
}

/**
* 初始化布局
*/
private void initView() {
btn_fragment_viewpager = (Button)findViewById(R.id.btn_fragment_viewpager);
btn_fragment = (Button)findViewById(R.id.btn_fragment);
btn_viewpager = (Button)findViewById(R.id.btn_viewpager);
}

/**
* 点击
* @param v
*/
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_viewpager:
startActivity(new Intent(this, MyViewPagerActivity.class));
break;
case R.id.btn_fragment:
startActivity(new Intent(this, MyFragmentActivity.class));
break;
case R.id.btn_fragment_viewpager:
startActivity(new Intent(this, MyFragmentViewPagerActivity.class));
break;

第一页是 listview

第二页是viewpager

第三页是textview

当然代码知识贴了第一阶段，还有里面的嵌套，还有嵌套的嵌套都没有贴出来，突然觉得好麻烦。哎。。。
