Disable or prevent multitouch in Activity

Question

I have several Views on an Activity which a user wants to touch quickly in succession and I capture these touches using a TouchListener and handling Motio

Answer 1

The best way to work around this scenario is to use a ViewGroup and implement the onInterceptTouchEvent method to manually route the touch events as you see fit.

This was originally answered here: Android multitouch! hack anyone?

Code implementing this solution (found in the comments section of the answer to the above question) is found here: http://pastebin.com/hiE1aTCw

Answer 2

The easiest way I found to force single touch across an entire app is to set it using a theme:

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowEnableSplitTouch">false</item>
    <item name="android:splitMotionEvents">false</item>
</style>

Manifest:

  <application
        android:label="@string/app_name"
        android:theme="@style/MyTheme" >

I have solved this using a custom method - which I did not want to do If anyone finds a better way I'd like to hear about it Thanks:

public static void setViewGroupEnebled(ViewGroup view, boolean enabled)
{
    int childern = view.getChildCount();

    for (int i = 0; i< childern ; i++)
    {
        View child = view.getChildAt(i);
        if (child instanceof ViewGroup)
        {
            setViewGroupEnebled((ViewGroup) child,enabled);
        }
        child.setEnabled(enabled);
    }
    view.setEnabled(enabled);
}

if someone still searching for best solution, put in the xml the following code :

android:splitMotionEvents = false 

Answer 5

I got it to work for me by just adding some code in OnTouchEvent method,

boolean action_down_required = false;

@Override
public boolean onTouchEvent(MotionEvent event) {

    int action = event.getAction();

    if(event.getPointerCount() > 1){
        action_down_required = true;
        return true;
    }

    if(action_down_required){
        action = MotionEvent.ACTION_DOWN;
    }

    switch (action) {
        case MotionEvent.ACTION_DOWN:

            // your code goes here...

            action_down_required = false;
            break;

        // Other events...

Answer 6

int currentapiVersion = android.os.Build.VERSION.SDK_INT;

            if (currentapiVersion >= android.os.Build.VERSION_CODES.HONEYCOMB) {

                horizentalLinearGridItem.setMotionEventSplittingEnabled(false);

            }

Here horizentalLinearGridItem is parentLayout view where we insert child views. In my code its LinearLayout. In this LinearLayout I added child views. But when I clicked two child views simultaneously, both were getting the events. To block that I used the above code.
