问题
This seems to be a very silly problem but its just not working for me.
I have 2 ImageButtons & a HorizontalScrollView(HSV) on a page. Strangely one of the Image Button(1st one) is not clicking. Also I wanted to make the HSV clickable so I used:
android:clickable="true", which does not work
You can use the xml & activity exactly as I have posted.
This is the xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/topRL"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/free_msgs_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="free msgs left" />
<ImageButton
android:id="@+id/buy_imageButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="@drawable/ic_launcher"
/>
</RelativeLayout>
<ListView
android:id="@+id/chat_page_listView"
android:layout_width="fill_parent"
android:layout_height="match_parent"
/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<HorizontalScrollView
android:id="@+id/chat_message_HSV"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="@+id/send_image_button"
android:clickable="true" />
<ImageButton
android:id="@+id/send_image_button"
android:layout_width="75dp"
android:layout_height="75dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="@drawable/ic_launcher" />
</RelativeLayout>
</RelativeLayout>
This is the activity file:
public class MainActivity extends Activity {
ImageButton buyIB;
ImageButton sendIB;
HorizontalScrollView chatMessageHSV;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
sendIB = (ImageButton) findViewById(
R.id.send_image_button);
chatMessageHSV = (HorizontalScrollView) findViewById(
R.id.chat_message_HSV);
buyIB = (ImageButton) findViewById(R.id.buy_imageButton);
buyIB.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Toast.makeText(MainActivity.this, "buy", Toast.LENGTH_SHORT)
.show();
}
});
chatMessageHSV.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "hsv", Toast.LENGTH_SHORT).show();
}
});
sendIB.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Toast.makeText(MainActivity.this, "send", Toast.LENGTH_SHORT).show();
}
});
}// end of onCreate
}
And I cant use button click like
public void onClick(View view)
{}
because the actual problem is containing a drawer layout where I'm using fragments & there this method doesn't work.

The problem in the ImageButton doesn't respond for you click because the ListView will respond first for the click because it above the ImageButton try to re order it , when i remove it the ImageButton respond for the click
about the HorizontallScrollView i found the solution to use the Touch Event instead of Click try this code
chatMessageHSV.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(ImageButtonActivity.this, "hsv",
Toast.LENGTH_SHORT).show();
}else if (event.getAction() == MotionEvent.ACTION_UP){
// here code if the touch up
}
return false;
}
});
feed me back

The ImageButton not clicking problem can be solved by adding to ListView these 2 lines:
android:layout_below="@+id/topRL"
android:layout_above="@+id/bottomRL"
