So I have tried this one tutorial which tells how the gestures work and I made a simple activity which detects the gesture and generates a toast. Now I am working on my project and made my homepage which has a simple Relative layout and an image view. The gestures work find there as well. Now I made a new Help page and tried everything I could but the gesture is not working for me. Is it because of the layout? as this one contains multiple relative and linear layouts.
Given below is my Help activity. I wanna open speech recognition on LongPress (I am trying a toast here but its not working)
Any help would be appreciated. I may be missing out something stupid

You are creating a GestureDetector but you are never "hooking it up" to your View. Try changing your onCreate like this:
super.onCreate(savedInstanceState);
View v = new RelativeLayout(this);
v.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
setContentView(v);
mDetector = new GestureDetectorCompat(this, this);
mDetector.setOnDoubleTapListener(this);
v.setOnTouchListener(new OnTouchListener(){
public boolean onTouch(View v, MotionEvent me){
return mDetector.onTouchEvent(me);
}
});
or you can try this
public boolean onTouchEvent(MotionEvent event) {
return gestureDetectorCompat.onTouchEvent(event)
}

I think onInterceptTouchEvent intercept them.
Well, you are returning true from onInterceptTouchEvent(), which means, that as a ViewGroup you do not want any touch event to be passed to children, instead pass that touch event to onTouchEvent().
You should listen for event in onInterceptTouchEvent() return false until you see that this is such a gesture, that shouldn't be handled by children. And on that point only you should return true.
I have a viewpager with several fragments in the viewpager.I need to handle click event.I have already implement the onTouch event,but its not trigger for click event.When i swiping onTouch is triggering.I don't know why it's not trigger for click event.

Now when i click it identified by the onInterceptTouchEvent in the ViewPagerWithTapGestreDetection class.So i need to view a Horizontal scrollbar when i click.Is it the correct way to call it inside onInterceptTouchEvent ?
As I'm new to android, My problem is I'm Developing an application I want to increment/decrement the numbers by clicking on the buttons in the home page,but first of all it should check for in the settings menu the check box is checked,if it is checked then only to perform the actions...

Do this, in your button click event code :
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
Intent startActivity = new Intent(this, Settings.class);
startActivityForResult(startActivity);
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
In settings do this :
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
Intent intent = getIntent();
if(isChecked)
intent.putExtra("Checked", true);
else
intent.putExtra("Checked",false);
setResult(i,100);
}
//put this in main activity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == 100) {
boolean val = data.getBooleanExtra("checked",false);
if(val==true)
//allow to increment decrement
else
//not
}
}
}
I have some ImageViews in my xml file. In my code section I want to move an image according to my wish. For that, I've done event.getx() and event.getY() and then use imageView.layout(). This process is not working. How can i move that image?
I think this might help:
package com.example.moveimageview;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.ImageView;
import android.widget.RelativeLayout;
public class MainActivity extends Activity {
ImageView im;
RelativeLayout rl;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting the wrapper layout from the xml
rl = (RelativeLayout) findViewById(R.id.relative1);
//getting the ImageView from xml
im = (ImageView) findViewById(R.id.myImageView);
rl.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent e) {
// TODO Auto-generated method stub
if(e.getAction()==android.view.MotionEvent.ACTION_DOWN)
{
//sending the new coordinates to the method
//that will change the view's location
setImageViewLocation(e.getX(), e.getY());
return true;
}
return false;
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private void setImageViewLocation(float x, float y)
{
//setting the coordinates
im.setX(x);
im.setY(y);
runOnUiThread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
im.invalidate();//invoking the view onDraw
}
});
}
}
(Edit) If you want to your ImageView around, here's the onTouchListner code for this (Same code as before just replace the OnTouchListner with this):
rl.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent e) {
// TODO Auto-generated method stub
if(e.getAction()==android.view.MotionEvent.ACTION_DOWN)
{
//sending the new coordinates to the method
//that will change the view's location
setImageViewLocation(e.getRawX(), e.getRawY());
return true;
}
if(e.getAction()==android.view.MotionEvent.ACTION_MOVE)
{
setImageViewLocation(e.getRawX(), e.getRawY());
return true;
}
return false;
}
});
