Clickable nested LinearLayout displaying AChartEngine dynamic graph

Question

I came across a post which exaplains that if I add android:onClick="OnClickMethod" to the <LinearLayout> in the XML file, and then in the JAVA file I add

    public void OnClickMethod(View v) {
    Intent intent= new Intent(getApplicationContext(), SecondActivity.class);
    startActivityForResult(intent, START_INTENT);
}

It should make the LinearLayout clickable. Which it does. But, I have the following setup in my XML file:

 <LinearLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:padding="0dp"
    android:id="@+id/linearLayout1"
    >
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:padding="5dp"
        >
    <ImageView
        android:id="@+id/imageView1"
        android:src="@drawable/myIcon"
        android:gravity="center_vertical|center_horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="2"
        />
    <TextView
        android:id="@+id/textView1"
        android:text="xxx"
        android:gravity="center_vertical|center_horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="2"
        android:textStyle="bold"
        />
    </LinearLayout>
    <LinearLayout 
        android:id="@+id/myChart" 
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1" 
        />

</LinearLayout>

If I add android:OnClick="OnClickMethod" to the linearLayout1 it makes only the TextView and Image clickable. But ideally I want the graph to be clickable. I tried adding android:OnClick="OnClickMethod" to myChart LinearLayout and it did not make that area clickable at all.

BTW, the myChart LinearLayout displays AChartEngine dynamic plot. and I disabled the X and Y pans so the user cannot move the graph around (renderer.setPanEnabled(false, false)

Please exaplain to me what I am doing wrong? I want the plot to be clickable. I feel that I am missing something.

Thanks

In order to add click interaction to your chart, you will have to enable the click interaction and add an OnClickListener on the chart view. You can see this working in this example, lines #156 to #176.
