Answer 1

Try this approach:

• add boolean doubleClick = false;
• and Handler doubleHandler
• in onClick check if doubleClick is true
• if true, this is a double click
• if not, set doubleClickto true and use handlers postDelayedto set it back to false after ie 500 ms

, onClick(), Handler, Handler onClick(). , onClick().

boolean isDoubleCliked=false;


Handler handler=new Handler();
Runnable r=new Runnable(){
  @Override
  public void run(){
    //Actions when Single Clicked
    isDoubleCliked=false;
  }
}

tv.setOnClickListener(new onClickListener){
  @Override
  public void onClick(View view){
    if(isDoubleClicked){
      //Actions when double Clicked
      isDoubleCliked=false;
      //remove callbacks for Handlers
      handler.removeCallbacks(r);
    }else{
      isDoubleCliked=true;
