android-homebutton

I'm currently working on an Android app. I would like to use the app icon in the action bar to navigate to the "home" activity. I read on this page that all that needs to be done is to add an onOptionsItemSelected and look for the id android.R.id.home . This is the code that I have implemented in my activity where I want to press the app icon to return to HomeActivity . @Override public boolean onOptionsItemSelected(MenuItem item) { switch(item.getItemId()) { case android.R.id.home: Intent intent = new Intent(this, HomeActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

Our app is crashing (it says "application has stopped) after we longpress the home button on samsung galaxy s3 (the longpress button is used to popup the multitasking screen/app switch dialog) we do not have this problem on our another testing device htc evo 3d so what is the keycode for this "action" ? and how can we disable this function ? This code sadly does not work: public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_APP_SWITCH) { System.exit(0); return false; } return super.onKeyDown(keyCode, event); } 来源： https://stackoverflow.com/questions/26554207

I've researched this a lot and it seems that after ICS normal applications can no longer intercept the Home Button. However, I see apps like Go Locker that are able to trap the Home Button. If Go Locker isn't intercepting the home button, what are they doing to prevent the user from going to the home screen? Illegal Argument You cannot intercept the home button. You cannot disable it. The way how the go locker does it is by drawing its layout over other apps. It requires extra permission. See this link for more details here. 来源： https://stackoverflow.com/questions/23772386/intercepting-home

I want to enable the home button in my fragment. This question is asked earlier but for an activity. I tried ... getSupportActionBar().setDisplayHomeAsUpEnabled(true); ... but this doesn't work. Here is my code: import com.actionbarsherlock.R; import com.actionbarsherlock.app.ActionBar; import com.actionbarsherlock.app.ActionBar.Tab; import com.actionbarsherlock.app.SherlockFragment; import com.actionbarsherlock.view.MenuItem; import android.support.v4.app.Fragment; import android.content.Intent; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import

In my application I need to send log-out request to server when ever user goes out of application via clicking on log-out button or closing application by pressing home button key. There is no problem with button and result is as I expect. The problem is how to get home button. Based on my research it is not possible to use onKeyDown(int keyCode, KeyEvent event) as we can use for getting back button. The solution that I'm thinking about is registering a receiver and sending a broadcast whenever Home button clicked. So through receiver I can launch a service to send log-out request to server.

We're trying to provide an application to the mentally and physically handicapped daughter of my neighbor that let's her use an Android tablet as a Talker, i.e., she presses a few big buttons and the devices generates speech. The application is basically a WebView and an additional object in Javascript used to perform and control the speech generation, plus some logic to handle the orientation changes. Html files are generated offline for her specific layout of the talking items. We've also added some music playing and picture viewing facilities to make the device more appealing to her.
