跳转到新的ACTIVITY,新的Activity采用的是FRAGMENT+TABHOST，跳转后当前的tabcontent内容为空，但是在新的Activity选项卡切换下，tabcontent的内容就又能显示了！！
问题就是跳转后，首次的tabcontent不显示！大家有谁遇到过这样的问题吗?
补充下code:
**前一个Activity， R.id.fragment_tab1 是用的Listfragment**
tabHost = (TabHost) findViewById(android.R.id.tabhost);
tabHost.setup();
tabHost.addTab(
tabHost.newTabSpec(main_home)
.setIndicator(main_home)
.setContent(R.id.fragment_tab1)
);
tabHost.setCurrentTab(0);
------------------------------------------------------------------------
R.id.fragment_tab1 里的setOnItemClickListener（）方法，是将当前list的item项放在通过intent传递到 ，需要启动的新的Activity中/
------------------------------------------------------------------------
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.showcontain);
ProgressRefresh();
}
private void ProgressRefresh(){
contextTask = new ContextTask(0);
TaskHost taskHost = new TaskHost(){
@Override
public void onPreExecute(int requestCode) {
// TODO Auto-generated method stub
super.onPreExecute(requestCode);
}
};
contextTask.setTaskHost(taskHost);
contextTask.setProgress(new SimpleDialogProgress(this, "加载LIST", "正在加载中..."));
InitUI();
contextTask.execute();
}
private void InitUI(){
getIntentExtra();
TextView txt = (TextView)findViewById(R.id.text_cjq);
txt.setText(texts);
InitTabHost();
InitClickListener();
}
private void InitTabHost(){
TabHost.TabSpec spec;
//tabHost = getTabHost();
tabHost = (TabHost) findViewById(android.R.id.tabhost);
tabHost.setup();
// .............
spec=tabHost.newTabSpec("Refresh").setIndicator("Refresh").setContent(R.id.tab0);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Love").setIndicator("Love").setContent(R.id.tab1);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Comment").setIndicator("Comment").setContent(R.id.tab2);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Onward").setIndicator("Onward").setContent(R.id.tab2);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Goback").setIndicator("Goback").setContent(R.id.tab1);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
}
private void InitClickListener(){
RadioGroup radioGroup=(RadioGroup) this.findViewById(R.id.main_tab);
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
switch (checkedId) {
case R.id.main_tab_addHome:
tabHost.setCurrentTabByTag("Refresh");
break;
case R.id.main_tab_addExam:
tabHost.setCurrentTabByTag("Love");
break;
case R.id.main_tab_myExam:
tabHost.setCurrentTabByTag("Comment");
break;
case R.id.main_tab_message:
tabHost.setCurrentTabByTag("Onward");
break;
case R.id.main_tab_settings:
tabHost.setCurrentTabByTag("Goback");
break;
default:
tabHost.setCurrentTabByTag("Refresh");
break;
}
}
});
}
private void getIntentExtra(){
Intent intent = getIntent();
title = intent.getExtras().getString("title");
texts = intent.getExtras().getString("texts");
resID = intent.getExtras().getInt("resIds");
}
spec=tabHost.newTabSpec("Refresh").setIndicator("Refresh").setContent(R.id.contain_tab0);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Love").setIndicator("Love").setContent(R.id.contain_tab1);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Comment").setIndicator("Comment").setContent(R.id.contain_tab2);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Onward").setIndicator("Onward").setContent(R.id.contain_tab0);
tabHost.addTab(spec);
spec=tabHost.newTabSpec("Goback").setIndicator("Goback").setContent(R.id.contain_tab1);
tabHost.addTab(spec);
问题就出现在这串代码里, 里面的TAG 与 setContent(R.id.contain_tab1);
不是一一对应的关系 , 原以为只要TAG值唯一就行了!..犯错了!!
之前为了图方便, 只在XML里写了3个tab 复用了2个tab用来测试,结果调了1天 ,,我靠靠靠靠靠,太悲剧了!!
你是不是用点击tab按钮的方法来触发tab间的切换的?
如果是的话,自己在代码里初始化的时候把它默认设置成第一个tab不就好了
现在做tab这种切换效果的话还可以使用ActivityGround来做
