i m getting a problem in back keyevent....method i m using is this

public boolean onKeyDown(int keyCode, KeyEvent event) {
if(keyCode==KeyEvent.KEYCODE_BACK){
}
}

when i click on back....it goes to my back screen after that i goes to the mainmenu
i dont kno y this happening

here mainmenu is the menu screen of the emulator

I'm not sure what your question is, but it's important whether you return True or False from the method. To quote the doc:

"If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false."

Hi guys.

Some time ago I was trying to handle the "back" key event, but it doesn't work as expected.
It continues propagating wheather you return true or false.

I think "home" and "back" key events cannot currently be managed this way...

No you can override the back key. I just reran my code and it still works as expected. I have an application with a webview, I wanted to override the back key in the case there were pages to go back, and otherwise to close the activity as normal. Here is said code:

public boolean onKeyDown(int keyCode, KeyEvent event){
if(keyCode==KeyEvent.KEYCODE_BACK){
if(ourWebview.canGoBack()){
ourWebview.goBack();
return true;
}else{
return super.onKeyDown(keyCode, event);
}
}
return super.onKeyDown(keyCode, event);
}

thanx dude no its working..but i hav one more problem
onDownKey event is not working with textview

My mistake.

I reviewed my test program, and the non-working keys were KEYCODE_HOME and KEYCODE_ENDCALL.

I'm glad you replied, and thus my mistake was clarified.

ansh.chauhan: Are you overriding the textview's onKeyDown method and it's not working ? if so, remember that your view has to be focussed so that it can receive the key event...

public class DisplayData extends TextView{
MainMenu mainMenu;
OnKeyListener keyListener;
public DisplayData(Context context) {

super(context);
Log.v("11111","111111111");
this.append("nnn"+AppConstant.title+":-");
this.append("nn"+AppConstant.data);
InfotainmentActivity.activity.setContentView(this);
this.setOnKeyListener(keyListener);
// TODO Auto-generated constructor stub
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

if(keyCode==KeyEvent.KEYCODE_BACK){
Log.v("2222","22222222");
mainMenu.STATUS=AppConstant.STATUS_SUNSIGN;
InfotainmentActivity.activity.setContentView(mainMenu);
return true;

}
return super.onKeyDown(keyCode, event);
}
