使用我的标签设置设计时遇到问题.所以我为tabHost中添加的每个tabspec创建了选择器.这是它的样子:

所以这是我的标签活动:

public class TabLayouts extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tabhost);

        TabHost tabHost = getTabHost();
        tabHost.getTabWidget().setStripEnabled(false);

        TabSpec latest = tabHost.newTabSpec(getString(R.string.latest_title));
        tabHost.setBackgroundResource(R.drawable.tabbar);

        // setting Title and Icon for the Tab
        latest.setIndicator(getString(R.string.latest_title), getResources().getDrawable(R.drawable.latest_albums_sel));
        Intent latestAlbums = new Intent(this, LatestAlbums.class);
        latest.setContent(latestAlbums);

        TabSpec favorites = tabHost.newTabSpec(getString(R.string.favorites_title));
        favorites.setIndicator(getString(R.string.favorites_title), getResources().getDrawable(R.drawable.favorites_sel));
        Intent favoritesInt = new Intent(this, Favorites.class);
        favorites.setContent(favoritesInt);

        TabSpec downloaded = tabHost.newTabSpec(getString(R.string.downloaded_title));
        downloaded.setIndicator(getString(R.string.downloaded_title), getResources().getDrawable(R.drawable.downloaded_sel));
        Intent downloadedIntent = new Intent(this, Downloaded.class);
        downloaded.setContent(downloadedIntent);

        tabHost.addTab(latest);
        tabHost.addTab(favorites); …

我正在尝试创建一个自定义视图 - 手指画,我遇到此错误的麻烦,我不知道如何解决它.谁能告诉我有什么问题？

我需要创建一个自定义布局，其中包含平板电脑上的两行，将显示特色项目和常规项目（无需滚动），并在手机上创建仅显示特色项目的列表视图。是否可以创建这样的布局，有人可以与我共享一些库来帮助我创建这种布局吗？

这是它在平板电脑上的外观：

这是它在手机上的外观：

我有一个包含主题标签的textview.#first #second #third.我的问题是如何检测单击哪个#标签,以便执行某些操作 - 例如.为这个词做吐司.这可能使用TextView小部件吗？我应该使用其他一些小部件吗？

UPDATE

我用这个例子找到了我的解决方案.希望将来能帮助别人!

我已将我的活动放在childview中,现在我无法显示来自我的活动和适配器的对话框.在我的logCat中我得到了

我有这样一张桌子:

<table id="someID">
<tr><td>example text</td></tr>
<tr><td>example text</td><td>example text</td></tr>
<tr><td>example text</td></tr>
<tr><td>example text</td><td>example text</td></tr>
</table>

我想只使用CSS隐藏表中的第二行和第三行.这个表是预定义的,所以我不能使用id或class标签来指定要设置样式的行,我正在寻找一些针对特定行的解决方案.

如果可以用CSS完成,有人可以告诉我如何做到这一点.

我有一个列表,其中我从共享首选项获得的具体数字(位置)应显示imageview(表示当前正在播放的歌曲).但我得到了这个位置,但该项目也显示在其他行上.滚动列表时出现问题.

*当我退出另一个活动时,就会发生这种情况,并且在我的简历上我会这样做:

@Override
protected void onResume() {
    super.onResume();
    if(AlbumDetails.mediaPlayer!=null)
    adapter = new PlaylistAdapter(this, songs);
    list.setAdapter(adapter);
}

这是我的代码:

public class PlaylistAdapter extends BaseAdapter {

    private Activity activity;
    private static LayoutInflater inflater = null;
    private ArrayList<Songs> data;
    private DatabaseHelper db;
    private SharedPreferences prefs;
    int playpos;

    public PlaylistAdapter(Activity a, ArrayList<Songs> songs) {
        activity = a;
        data = songs;
        db = new DatabaseHelper(a);
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        prefs = activity.getSharedPreferences("com.darkovski.quran",
                Context.MODE_PRIVATE);
        playpos = prefs.getInt("posPlaying", -1);
    }

    public int getCount() {
        return data.size();
    } …

我从eclipse导出了一个项目 - 但是现在我无法将支持库添加到我的项目中compile 'com.android.support:support-v4:21.0.0'因为这个项目中使用的库有自己的同一个库的副本(但是它们在它们的libs文件夹中的jar文件中) .现在,当我添加时,compile 'com.android.support:support-v4:21.0.0'我得到了这个问题:

Error:Execution failed for task ':Athan:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: android/support/annotation/IntDef.class

有人可以帮我解决这个问题吗？
