Question

我使用选项卡构建自己的网络浏览器。我的问题是，当我关闭一个选项卡并返回另一个选项卡时，如果我单击当前选项卡，那么我会得到关闭选项卡的内容。这是我的代码：

private void addMethod() {
    //tring webSiteName = getHost("http://www.google.com");
    Intent openBrowser = new Intent();
    openBrowser.setClass(this, WebBrowser.class);
    tabHost.addTab(tabHost.newTabSpec("http://www.google.gr" + Integer.toString(z)).setIndicator("ΚΑΡΤΕΛΑ ").setContent(openBrowser));
    tabHost.setCurrentTab(z);
    Log.d("z",Integer.toString(z));
    ++z;
}

private void deleteMethod() {
    // Since we can't really delete a TAB
    // We hide it

    int position = tabHost.getCurrentTab();
    Log.d("Position",Integer.toString(position));

    if (position != 0 ) {
        tabHost.getCurrentTabView().setVisibility(1);
        tabHost.setCurrentTab(position-1);
    }
    else if(position== z){
        tabHost.getCurrentTabView().setVisibility(1);
        tabHost.setCurrentTab(position+1);
    }
    Log.d("Z val in delete()",Integer.toString(z));
    if(position >0)
    {
        tabHost.getCurrentTabView().setVisibility(View.GONE);
        tabHost.setCurrentTab(position+1);
        z-=1;
        if(z<0)
            z=0;
    }
    else if(position == 0)
    {
        tabHost.getCurrentTabView().setVisibility(View.GONE);
        tabHost.setCurrentTab(position+1);
        z=0;
    }
    else if(position == z)
    {
        tabHost.getCurrentTabView().setVisibility(View.GONE);
        tabHost.setCurrentTab(z-1);
        Log.d("Z value in final","lol");
        Log.d("Pos",Integer.toString(position));
        Log.d("z pos",Integer.toString(z));

        z--;
    }
