不可能点击一个按钮 [英] Not possible to click a Button

问题描述

我在与被显示在屏幕上的一个按钮一个奇怪的问题，但是我无法点击。这并不是说在的onClick 事件不点火，似乎身体不反​​应的点击，因为如果它有它的顶部透明层。

I'm having a weird issue with a button that is being shown on screen, but that I can't click. It is not that the onClick event is not firing, it seems that physically it does not react to clicks, as if it had a transparent layer on top of it.

主要活动其中，它是建立在：

The main Activity where it is built on:

public class MusicList extends Activity implements OnClickListener {
...
@Override
    public void onCreate(Bundle bundle)
    {
        super.onCreate(bundle);     

        setContentView(R.layout.mymusic);
        this.myTabHost = (TabHost)this.findViewById(R.id.th_set_menu_tabhost); 
        this.myTabHost.setup(); 

        TabSpec ts = myTabHost.newTabSpec("TAB_TAG_1");

        ts.setIndicator("Media Item",getResources().getDrawable(R.drawable.music));             

        ts.setContent(R.id.media_item_tab);

        try {
            relativeLayout = (RelativeLayout) myTabHost.findViewById(android.R.id.tabcontent).findViewById(R.id.media_item_tab);
        } catch (NullPointerException e) {
            Log.e(this.getClass().getSimpleName(),"Layout is not correct",e);
        }

            Button button = (Button)relativeLayout.findViewById(R.id.play_button);
            // button.setClickable(true);
            button.setOnClickListener(this);
                    myTabHost.addTab(ts);
    }
    @Override
    public void onClick(View v) {
        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(itemData.get("ITEM_URL"))));
    }
}

布局，这是完美的显示在屏幕上是这样的：

The layout, which is shown perfect on screen is like this:

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/th_set_menu_tabhost" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 
     <TabWidget 
          android:id="@android:id/tabs" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"/>
     <FrameLayout 
          android:id="@android:id/tabcontent" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent" 
          android:paddingTop="65px">

            <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/media_item_tab"

            </RelativeLayout>
          <ListView
          android:id = "@+id/tablist"
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"
          /> 
     </FrameLayout> 
</TabHost>

有什么建议？

谢谢！

推荐答案

您有一个的FrameLayout 有两个孩子时，它仅用于主机之一。在的ListView 最后补充说，最终会在顶部，很可能接收所有的输入。

You have a FrameLayout with two children when it's only intended to host one. The ListView was last added, will end up on top and is probably receiving all of your input.
