我正在实现视图寻呼机,我想放在dot(.)底部而不是滑动选项卡.我该怎么办.谢谢你的帮助

而不是这个

我想这样做

我创建了导航抽屉并在列表中显示项目.我的列表是静态的,但我正在显示点数.因此,当用户选择列表中的项目并执行某些活动时,他会获得积分.所以我想尽快更新积分.我怎样才能做到这一点./

以下是我的代码:

活动类:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home_page);
    // Initializing
    dataList = new ArrayList<DrawerItem>();
    mTitle = mDrawerTitle = getTitle();
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);

    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
            GravityCompat.START);

    sharedPreferences = getSharedPreferences(Constant.LOGIN_CHECK,
            Constant.PRIVATE_MODE);
    editSharedPreferences = sharedPreferences.edit();
    if (sharedPreferences.getBoolean(Constant.IS_ALREADY_LOGIN,
            false)) {
        loginInBackground();
    }
    String p1 = sharedPreferences.getString(Constant.USERS_POINTS,
            "");
    String p2 = sharedPreferences.getString(
            Constant.LEVEL_ONE_POINTS, "");
    String p3 = sharedPreferences.getString(
            Constant.LEVEL_TWO_POINTS, "");

    String pointText = " POINTS";
    dataList.add(new DrawerItem("OVERVIEW", R.drawable.ic_action_eye,
            Color.DKGRAY, Color.TRANSPARENT));
    dataList.add(new DrawerItem("EARN POINTS", R.drawable.ic_action_dollor,
            Color.GREEN, Color.TRANSPARENT));
    dataList.add(new DrawerItem("MY …

我正在. In that case I want to put我的主屏幕上创建"我自己的启动器快速搜索栏",即谷歌现在发射器.

我怎样才能做到这一点.我已经通过多个线程但没有找到任何相关的答案.

我不想显示widget picker.我希望asap用户安装此启动器搜索栏应该在那里.

提前致谢.

我需要在android中显示Alertdialog内部Asynctask,但它不会在throws异常中显示.

05-13 14:59:35.522: WARN/System.err(1179): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

谢谢.

也许我只是因为好奇而问错了问题.我通过扩展数组适配器来创建自定义适配器.现在我想在GridView中显示它.我已经阅读了很多文章,我发现它们只使用基本适配器来显示GridView.请大家告诉我这背后的逻辑是什么？我们可以使用Array适配器代替Base Adapter吗？

我有一个列表视图,其中包含复选框.对于每个复选框(它们大约为3),它具有特定的AsyncTask.

我永远不知道用户选择什么样的复选框,所以我不能将异步任务放在AlertDialog的末尾,因为我永远不知道用户是否只选择了一个复选框,或者两个或三个.

因为AsyncTask是按步骤执行的(仅当第一个Async完成时才是第二个开始),我想到了一个新的AsyncTask与AlertDialog的结尾.

private class showMessageAsync extends AsyncTask<Void, Integer, String> {
    @Override
    protected String doInBackground(Void... params){
        AlertDialog alertDialog;
        alertDialog = new AlertDialog.Builder(getApplicationContext).create();
        alertDialog.setTitle("The Process");  
        alertDialog.setIcon(R.drawable.success);
        alertDialog.setCanceledOnTouchOutside(false);
        alertDialog.setMessage("All done!");  
        alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                              new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                Intent A = new Intent(DownloadActivity.this, Menu_activity.class);
                startActivity(A);
                finish();
            }
        });
        alertDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {          
            @Override
            public void onDismiss(DialogInterface dialog) {
                Intent A = new Intent(DownloadActivity.this, Menu_activity.class);
                startActivity(A);
                finish();
            }
        });
        alertDialog.show();
        return "Executed";
    }
}

这是错误:

我有一个菜单项,我想以编程方式更改其可见性.菜单就是这个
