我是开发的android应用程序。我已经完成了更多工作,但我想尽量减少选择。我已经使用了标签栏。在那我想最小化标签。当用户单击最小化选项卡以最小化整个应用程序时。
我的标签栏代码为..
public class tabbar extends TabActivity implements OnTabChangeListener {
private Context mContext;
TabHost tabHost;
int tabload=0;
private AlertDialog alertDialog;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabbar);
//mContext=this;
/** TabHost will have Tabs */
tabHost = (TabHost)findViewById(android.R.id.tabhost);
tabHost.setOnTabChangedListener(this);
/** TabSpec used to create a new tab.
* By using TabSpec only we can able to setContent to the tab.
* By using TabSpec setIndicator() we can set name to tab. */
/** tid1 is firstTabSpec Id. Its used to access outside. */
TabSpec firstTabSpec = tabHost.newTabSpec("tab_id1");
TabSpec secondTabSpec = tabHost.newTabSpec("tab_id2");
TabSpec thirdTabSpec = tabHost.newTabSpec("tab_id3");
/** TabSpec setIndicator() is used to set name for the tab. */
/** TabSpec setContent() is used to set content for a particular tab. */
firstTabSpec.setIndicator("FRIENDS").setContent(new Intent(this,view_friends.class));
secondTabSpec.setIndicator("GROUPS").setContent(new Intent(this,groups.class));
thirdTabSpec.setIndicator("SIGN OUT").setContent(new Intent(this,signout.class));
/** Add tabSpec to the TabHost to display. */
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(thirdTabSpec);
}
@Override
public void onTabChanged(String tabId) {
// TODO Auto-generated method stub
for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
{
tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#343333")); //unselected
}
tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#f1a026")); // selected
// if(tabId.equals("tab_id1")){
// LocalActivityManager manager = getLocalActivityManager();
// manager.destroyActivity("tab_id1", true);
// manager.startActivity("tab_id1", new Intent(this, view_friends.class));
// }
}
@Override
protected void onDestroy() {
super.onDestroy();
tabHost.setCurrentTab(2);
System.gc();
}
}
在此代码中,如果需要任何更正,请帮助...
给我一个示例代码。
最佳答案
我不确定最小化是什么意思。如果要隐藏应用程序并向用户显示主屏幕,则可以使用以下意图。
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);
尽管如果用户要隐藏您的应用程序,“主页”按钮已绰绰有余
