本文实例为大家分享了Android仿新浪微博分页管理界面的具体代码，供大家参考，具体内容如下
多个activity分页管理，为了方便获取上下文，采用继承TabActivity的传统方法。
大致思路：使用RadioGroup点击触发不同的选卡项，选卡项绑定不同的activiity,进而进行分页管理。详解见注解。
public class MainActivity extends TabActivity {
//定义TabHost对象
private TabHost tabHost;
//定义RadioGroup对象
private RadioGroup radioGroup;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_layout);
initView();
initData();
}
private void initView() {
//实例化TabHost，得到TabHost对象
tabHost = getTabHost();
//得到Activity的个数
int count = Constant.ConValue.mTabClassArray.length;
for (int i = 0; i < count; i++) {
//为每一个Tab按钮设置图标、文字和内容
TabSpec tabSpec = tabHost.newTabSpec(Constant.ConValue.mTextviewArray[i])
.setIndicator(Constant.ConValue.mTextviewArray[i]).setContent(getTabItemIntent(i));
//将Tab按钮添加进Tab选项卡中
tabHost.addTab(tabSpec);
}
//实例化RadioGroup
radioGroup = (RadioGroup) findViewById(R.id.main_radiogroup);
}
private void initData() {
// 给radioGroup设置监听事件
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.RadioButton0:
tabHost.setCurrentTabByTag(Constant.ConValue.mTextviewArray[0]);
break;
case R.id.RadioButton1:
tabHost.setCurrentTabByTag(Constant.ConValue.mTextviewArray[1]);
break;
case R.id.RadioButton2:
tabHost.setCurrentTabByTag(Constant.ConValue.mTextviewArray[2]);
break;
case R.id.RadioButton3:
tabHost.setCurrentTabByTag(Constant.ConValue.mTextviewArray[3]);
break;
case R.id.RadioButton4:
tabHost.setCurrentTabByTag(Constant.ConValue.mTextviewArray[4]);
break;
}
}
});
((RadioButton) radioGroup.getChildAt(0)).toggle();
}
private Intent getTabItemIntent(int index) {
Intent intent = new Intent(this, Constant.ConValue.mTabClassArray[index]);
return intent;
}
}
MainActivity布局文件tab_layout.xml. TabHost布局，添加一个TabWidget用于显示activity，下面是一个RadioGroup显示切换activity的按钮菜单。
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
