Menu
I have created one image button in android, but when I am clicking on that button nothing is happening. I have set all the properties but still nothing is happening. So can you help me that where I am wrong.
xml file
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
android:id="@+id/widget39"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<EditText
android:id="@+id/editText1"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_x="0dp"
android:layout_y="3dp" />
<ImageButton
android:id="@+id/search"
android:layout_width="40dp"
android:layout_height="41dp"
android:layout_x="312dp"
android:layout_y="10dp"
android:clickable="true"
android:onClick="onClick"
android:background="@drawable/search" />
/>
</AbsoluteLayout>
search.java
public class SearchData extends Activity {
ImageButton search;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_data);
search =(ImageButton)findViewById(R.id.search);
search.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
try {
ConnectService();
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

To make a View clickable so that users can tap (or click) it, add the android:onClick attribute in the XML layout and specify the click handler. For example, you can make an ImageView act like a simple Button by adding android:onClick to the ImageView . In this task you make the images in your layout clickable.
Onclick in XML layoutWhen the user clicks a button, the Button object receives an on-click event. To make click event work add android:onClick attribute to the Button element in your XML layout. The value for this attribute must be the name of the method you want to call in response to a click event.
View. OnClickListener is an interface, which defines the onClick(View) method. If you have a class which intends to listen for clicks, you should both implement the interface (if not already extending a class that does), and implement this method too. You have to use both; they're not somehow alternatives.
<ImageButton
android:id="@+id/search"
android:layout_width="40dp"
android:layout_height="41dp"
android:layout_x="312dp"
android:layout_y="10dp"
android:clickable="true"
android:onClick="onClick"
android:background="@drawable/search" />
As per your xml you should remove android:onClick="onClick" line from your Image button Xml.Then it will work because 1st priority will go for always onClick method what you mentioned in xml.
