This is my code: package com.testappmobile; import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.view.Window; import android.webkit.WebChromeClient; import android.webkit.WebView; import android.webkit.WebViewClient; public class testappmobileActivity extends Activity { final Activity activity = this; private WebView webview; @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // Check if the key event was the BACK key and if there's history if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) { webview.goBack(); return

The following code causes a back arrow to appear in the ActionBar: getSupportActionBar().setDisplayShowHomeEnabled(true); getSupportActionBar().setDisplayHomeAsUpEnabled(true); I'm looking for the resource ID of the arrow drawable, i.e. android.R.drawable.xxx. The reason I need this ID is so that I can manually set an identical arrow (size & colour) elsewhere in my app. I tried making my own drawable and using that but the size was different from the one in the ActionBar. If you have the support library in your project, you can make a back button in any place in your applicaction like this:

I have a Notes-like app: uitableviewcontroller showing up individual notes by pushing them onto navigation stack). And I decided to use an ios7 Back button and a pan gesture recognizer coming with it. My only modification is removing text from the button by setting navigationItem title of the from-controller to an empty string before pushing the detail-view-controller, as it is advised at https://stackoverflow.com/questions/18870128/ios-7-navigation-bar-custom-back-button-without-title The button itself works just fine, but when I am going back from my note to the notes table view by means of

I'm trying to figure out how to create a back button that allows the user to go back one page. I read through Apple's Docs (which still go way over my head) and found out that I need to setup the canGoBack and goBack 's. I have tried this, but for some reason it is not working. My UIWebView is named viewWeb , and I created and attached an outlet to my Back button, named backButton , and also tagged it as 1.

I sent a task (activity) to back with: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); moveTaskToBack(true); } but I need bring it to front by setOnClickPendingIntent in widget. Just start the main (root) activity of your application like this: Intent intent = new Intent(context, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); If the activity is already running in a task, this will just bring that task to the foreground (without creating any new

Say I have 3 Activities in my application: A, B and C. The flow though the application is: A -> B -> C. Once at C, pressing the back button will take the user to B. If the user presses the back button another time they got to A, and finally if they press it one more time, they exit the application. Objective: When the user presses the back button on C, they should go to A and not B, and if they press it another time, they exit the app. Problem: When overriding the back button on Activity C to launch Activity A everything appears to be ok. However if the user presses the back button again, they
