设置viewpager中的控件点击事件

public void start(View v) {//在button等控件的xml文件中添加android:onClick="start"
		switch (v.getId()) {
		case R.id.btn_1:
		case R.id.btn_2:
			mViewPager.setCurrentItem(++index);
			break;
		case R.id.btn_3:
			finish();
			break;
		}
	}

如果想把布局文件换成Activity
首先初始化

LocalActivityManager manager = new LocalActivityManager(this , true);
manager.dispatchCreate(savedInstanceState);
manager.startActivity(id, intent).getDecorView();

在添加布局文件是改为

listViews.add(getLocalActivityManager().startActivity("1", new Intent(Hdjl.this, Hdjl_cx.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView());
