[android-developers] Re: How to startup one application programmatically from other application
I should made it more clear, i intent to let user specific the time to fire the chosen app. Which approach is better? notification or call intent from AlarmManger? Please be noted that the app B or C will be the existence third part application, i may not know which activity is the entry point.

You can for instance use the AlarmManager and then just fire a suitable Intent, but the user might be in the middle of (say) enter a password or similar when you happen to pop up app B/C, so this app had better be as important as a phone call or similar. A better approach might be to use a notification. Best / Jonas -- You received this message because you are subscribed to the Google Groups Android Developers group.

Well, that will be similar with handling the checkbox in the item.
I handled it in my customized adapter with a dirty approach.

I used to define the receiver in manifest xml to autostart the activity, this is working good. receiver android:enabled=true android:name=.BootUpReceiver android:permission=android.permission.RECEIVE_BOOT_COMPLETED intent-filter action android:name=android.intent.action.BOOT_COMPLETED / category android:name=android.intent.category.DEFAULT / /intent-filter /receiver Say my application has the main acticity class A as entry point and another class B with just a funtion called fireSomeAction. Now after android reboot, i want to call the fireSomeAction function in class B for only once, how can i do that? Move fireSomeAction() into BootUpReceiver and call it from there. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://github.com/commonsguyhttp://commonsware.com/blog|http://twitter.com/commonsguy Android Training...At Your Office:http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] TableRow Layout issue on ImageView
This should be a very simple one but i can never feel comfortable after tried so many options. I've defined a text view in left and a image view in right in a TableRow, no matter what i tried, the image always aligns to the right side. I found out that it's because the text view occupies most of the width in the line that leaves no more space for the image, but just don't know how to correct it. TableRow LinearLayout android:orientation=horizontal android:layout_width=fill_parent TextView android:textSize=20sp android:textStyle=bold android:id=@+id/my_title android:text=abc android:layout_height=wrap_content android:layout_width=fill_parent android:layout_weight=1 /TextView ImageView android:id=@+id/phone_mode_icon android:src=@drawable/ ic_airplane android:layout_width=wrap_content android:layout_height=wrap_content android:layout_gravity=center_vertical / /LinearLayout /TableRow Please help me out, thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

builder.setTitle(Brightness);
builder.setPositiveButton(Ok, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
/// The seekBar here is a null point however?
SeekBar seekBar = (SeekBar)
findViewById(R.id.seekbar);
int progress = seekBar.getProgress();
Log.v(TAG, = progress is : +
progress);
}
});

You are calling findViewById() on your activity. Your activity
presumably does not have a SeekBar named R.id.seekbar.
Try calling layout.findViewById(R.id.seekbar) instead.

[android-developers] Frustrated with CheckBox/CheckedListView in listview
Dear all,
I've tried my every effort to fight with this issue for two days but
no any luck.
What I want to do is: Display a list view with 3 elements: title,
subtitle and a checkbox. It will be ideal that the event handler only
fires when user click on the CheckBox but not the list item.
I start with the CheckedListView first but it seems this component
didn't provide a good interface to populate two properties as one
component.
Then I was think if it's possible to directly use the checkbox and
catch the onlick event?
I then created a customized View Adapter:
public class ProfileAdapter extends SimpleAdapter {
...
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row =
this.mContext.getLayoutInflater().inflate(R.layout.list_profile,
null);
row.setTag(R.id.profile_title,
row.findViewById(R.id.profile_title));
row.setTag(R.id.profile_value,
row.findViewById(R.id.profile_value));
row.setTag(R.id.cb_switch, row.findViewById(R.id.cb_switch));
row.setTag(R.id.id, row.findViewById(R.id.id));
TextView profileTitle = (TextView)
row.getTag(R.id.profile_title);
TextView profileValue = (TextView)
row.getTag(R.id.profile_value);
cb = (CheckBox) row.getTag(R.id.cb_switch);
TextView id = (TextView) row.getTag(R.id.id);
// this map was filled in my list activity class which
contains key: title, value, enable and id
MapString, String temp = (MapString, String)
((AdapterView?) parent).getItemAtPosition(position);
profileTitle.setText(temp.get(title));
profileValue.setText(temp.get(value));
profileValue.setText(temp.get(value));
String sid = (String)temp.get(id);
id.setText(sid);
cb.setChecked(isEnable(temp.get(enable)));
cb.setFocusable(false);
cb.setOnCheckedChangeListener(new
OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean
isChecked) {
Log.v(test, ** sid is: + sid);
//mProfileDao.updateEnable(mId, isChecked);
//Toast.makeText(mContext,
getToastMessage(isChecked),
Toast.LENGTH_SHORT).show();
}
});
I tried to use onCheckedChanged to capture the CheckBox click event
but there is way to detect the position of the item clicked??? I doubt
if is this the right place or right way to do it.
Please kindly help... thanks millions
