I am using a list view containing check boxes....could u please help me how to identify which check box has the user selected
basically I want different functions to be performed when checkbox is clicked or listitem is selected similar to android alarm clock..
I am new so I may not explain the situation well. Please let me know if you need more info.
I am trying to implement a listview like this:
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
I want other checkbox unchecked automatically when I click one of them. So it is like a single choice. I write following codes which can implement multiple choice but when I try to switch it to single choice I got trouble.
in checkBoxOnClickListener I cannot find other (checkbox)view and toggle them. Any suggestion pals? Let me know if you think my express skills poor. code...
Currently I have a list view within it each row has a checkbox attached. I would like that once any checkbox is checked, at the bottom of the screen a view displays, and once none of the checkboxes are checked, the view automatically disappeared. Possible to do this?
View 2 Replies View RelatedI'm sure this is an obvious one but I'm at a loss. I'm using my own layout for list rows, all well and fine. but the moment I add a checkbox view to the rows layout only the checkbox responds to user selection. I'd like for the checkbox to change state if the user taps anywhere within a given row. (as with android prefs)

View 1 Replies View RelatedI am new to android, and ended up (have to) ask a question here. Let's make it simple, I simply want to make my own TextView-like (MyView extends View), This is my code:
public class MyView extends View { private Paint mPaint;
private String mText; private Bitmap mBitmap1; private Bitmap mBitmap2;
public MyView(Context context) { super(context); initView(); }
public MyView(Context context, AttributeSet attrs) { super(context, attrs);
initView(); } private final void initView() { mPaint = new Paint(); }
public void setText(String text) { mText = text; }
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int measuredWidth = measureWidth(widthMeasureSpec);
if (mBitmap1 == null) initBitmap1(measuredWidth);
int measuredHeight = measureHeight(heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
}
private void initBitmap1(int measuredWidth) {
mBitmap1 = Bitmap.createBitmap(measuredWidth, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap1 ); canvas.drawText(mText, 0, 0, mPaint);
} private void initBitmap2() {
mBitmap2 = Bitmap.createBitmap(30, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap2); canvas.drawText(mText, 0, 0, mPaint);
} private int measureWidth(int widthMeasureSpec) {
int measuredWidth = 0; int specWidthMode = MeasureSpec.getMode(widthMeasureSpec);
int specWidthSize = MeasureSpec.getSize(widthMeasureSpec);
if (specWidthMode == MeasureSpec.EXACTLY) { measuredWidth = specWidthSize;
} else { measuredWidth = getWidth(); if (specWidthMode == MeasureSpec.AT_MOST) {
measuredWidth = Math.min(measuredWidth, specWidthSize);
} } return measuredWidth; }
private int measureHeight(int heightMeasureSpec) {
int measuredHeight = 0; int specHeightMode = MeasureSpec.getMode(heightMeasureSpec);
int specHeightSize = MeasureSpec.getSize(heightMeasureSpec);
if (specHeightMode == MeasureSpec.EXACTLY) { measuredHeight = specHeightSize;
} else { measuredHeight = 80; if (specHeightMode == MeasureSpec.AT_MOST) {
measuredHeight = Math.min(measuredHeight, specHeightSize);
} } return measuredHeight;
} @Override protected void onDraw(Canvas canvas) {
super.onDraw(canvas); canvas.drawBitmap(mBitmap1, getLeft(), 0, mPaint);
initBitmap2(); canvas.drawBitmap(mBitmap2, getLeft(), 30, mPaint);
} }
In my code, I populate some numbers of MyView (let's say 20) in a ListActivity. My question is why mBitmap1's order changes randomly while i scroll (up-down) fastly (if I scroll slowly, this problem not occur)? mBitmap2 stays where those should be.
How do I listen to the event when a checkbox is selcted/unselected?
View 2 Replies View RelatedI am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

View 1 Replies View RelatedI kind of have a 2 part question here.
1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?
2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.

View 3 Replies View RelatedI have simple list to be filled in from the database along with a checkbox. I need a handle to all the checkboxes selected. Whn the CLEAR button is pressed at that point I need the row ids of all the selected check boxes to delete them. To do this :
My list.xml file looks like this :
CODE:......
and my data_entry.xml looks like this:
CODE:............
Now: I have list.java file where I am populating the list as follows:
CODE:.....................
Now where do i give the handle to the heckbox cause anywhere else it would give me a null exception as the data_entry contains the checkboxes. Plus I need a listener to handle the checkbox status?

I'm trying to bind data from my SQLiteDatabase to a ListView. I'm currently using a SimpleCursorAdapter to fill in my ListView. Unfortunately this doesn't seem to work with setting a CheckBox's checked attribute. This is how I do it now; instead of changing the CheckBox's checked status the adapter is filling in the value to the text argument, so the value is displayed right of the CheckBox as text.
Java:
setListAdapter( new SimpleCursorAdapter( this, R.layout.mylist, data,
new String[] { Datenbank.DB_STATE, Datenbank.DB_NAME }, new int[] { R.id.list_checkbox, R.id.list_text } ) );
mylist.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" >
<CheckBox android:text="" android:id="@+id/list_checkbox"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:checked="false" > </CheckBox>
<TextView android:text="" android:id="@+id/list_text" android:layout_width="wrap_content"
android:layout_height="wrap_content" > </TextView> </LinearLayout>
The field in the database is of course of type boolean and I've also tried to assign an id to the checked field to fill the value in.
I think I've tried everything(made focusable:false!!) and I cant capture in anyway the selected checkbox on my list item. Even OnItemClickListener, doesn't respond to any click. How can I retrieve checked checkboxes in my list item? My list item included: image view, 4 textviews and the checkbox. Some code:
this is in my ListActivity class:
final String columns[] = new String[] { MyUsers.User._ID, MyUsers.User.MSG, MyUsers.User.LOCATION }; int[] to = new int[] { R.id.toptext, R.id.bottomtext,R.id.ChkBox, R.id.Location}; Uri myUri = Uri.parse("content://com.idan.datastorageprovider/users"); Cursor cursor = getContentResolver().query(myUri, columns, null, null, null); startManagingCursor(cursor); ListCursorAdapter myCursorAdapter=new ListCursorAdapter(this, R.layout.listitem, cursor, columns, to); this.setListAdapter(myCursorAdapter);
And this is my Custom Cursor adapter class:
public class ListCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public ListCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout;
} @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); return v;
} @Override public void bindView(View v, Context context, Cursor c) { TextView topText = (TextView) v.findViewById(R.id.toptext); if (topText != null) { topText.setText("");
} int nameCol = c.getColumnIndex(MyUsers.User.MSG); String name = c.getString(nameCol); TextView buttomTxt = (TextView) v.findViewById(R.id.bottomtext); if (buttomTxt != null) { buttomTxt.setText("Message: "+name); } nameCol = c.getColumnIndex(MyUsers.User.LOCATION);
name = c.getString(nameCol); TextView location = (TextView) v.findViewById(R.id.Location);
if (locationLinkTxt != null) { locationLinkTxt.setText(name);
}
I've tried many ways. many listeners, can't figure how to capture listener to my checkboxes. The data I am binding to the list items from the database, isn't concerned about the checkbox.. only the textviews. There isn't any connection between the database and the checkbox I have in the list's item.
