I have been trying to resolve this now for a number of days, I have searched the web and have also scoured through the many related questions provided on here but I am yet to resolve this issue.
The code works fine when I create a separate project, but the some reason it is not working here.
I have several activities that are accessible buy a click of a button from the main page (This part is working fine) and then from each of those several activities I have buttons that when clicked should open a website, but it is not happening.....
I have added all activities to the Manifest ( what I can see) have looked at it several times. lol
I've redone the code several times but to no avail, the only thing I have not done is start the project from scratch (Last resort).
Appreciate your help.

Not completely sure if this is correct.
#Override is missing in onCreate of all the webview activities defined by you.
Check if the onCreate() is getting triggered at all.

dont pay attention to the "scrollview" (i dont think the problem is there), just look at the end of the code for the 2 imagebuttons..
and this the java code for Settings:
public class Settings extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.my_settings);
//code...
ImageButton goBack=(ImageButton)findViewById(R.id.st_ibt1);
ImageButton about=(ImageButton)findViewById(R.id.st_ibt2);
goBack.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent intent=new Intent(Settings.this, MainActivity.class);
startActivity(intent);
//finish();
}
});
about.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent intent=new Intent(Settings.this, About.class);
startActivity(intent);
//finish();
}
});
}
so, how to fix this? i dont understand what this error means.. any suggestions
I think the problem is :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true"
android:orientation="vertical" >
You enable focus to this LinearLayout, but you didn't provide any id for it.
I have a simple app that updates a counter with plus/minus buttons. I have implemented onClickListeners but I can't get the counter to update based on clicks. I am running my app in an emulator, the application uploads and installs successfully. I also don't see the print statements in the logcat. Please help. Thank you.

You should probably just declare a new View.OnClickListener() rather than having Main activity implement it... that just seems weird to me. Then set the click listener to that
i want to put listview into a layout and i want to use just Activity class , not listActivity, i saw these two questions
First
Second

compare with your code if anything is missed.
Replace width="match_parent" of listview and width="40dp" of linear to 0dp
Adjust your weights accordingly like 0.8 for list and 0.2 for linear etc

My Code:
public class My_Application extends Activity {
public ToggleButton privBtn = (ToggleButton) findViewById(R.id.privacyShow);
public LinearLayout privLay = (LinearLayout) findViewById(R.id.privacyLayout);
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
privBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(privBtn.isChecked()) {
privLay.setVisibility(LinearLayout.VISIBLE);
}
else {
privLay.setVisibility(LinearLayout.INVISIBLE);
}
}
});
}
}

You can't set the privBtn and privLay before the setContentView() is called. Move those two statements into your onCreate().
public class My_Application extends Activity {
public ToggleButton privBtn;
public LinearLayout privLay;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
privBtn = (ToggleButton) findViewById(R.id.privacyShow);
privLay = (LinearLayout) findViewById(R.id.privacyLayout);
privBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(privBtn.isChecked()) {
privLay.setVisibility(LinearLayout.VISIBLE);
}
else {
privLay.setVisibility(LinearLayout.INVISIBLE);
}
}
});
}
}
