I was wondering if its possible to block the onclick events on a layout and all the children inside the layout.
for example, I have a LinearLayout and inside that I have buttons and an editText. At a certain point I don't want the user to click on the buttons or edit the text. Is there a way to block that? Do I have to do it for each view? or I can do it for a Layout? What is the best way to do this?

I have a LinearLayout with 2 text View as its children. How can I make the children of LinearLayout to change foreground color (in this case, the text color of the text view) when the linearlayout has focus?
<LinearLayout> <TextView android:id="@+id/name" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:textAppearance="?
android:attr/textAppearanceSmall" android:textColor="?android:attr/textColorInverse" />
<TextView android:id="@+id/value" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:textAppearance="?
android:attr/textAppearanceSmall" android:textColor="?android:attr/textColorInverse" />
</LinearLayout>
I loved the camera on the Eris and the Incredible, not only did they have a whole lot more of a crisp high-res detail, the auto-focus absolutely rocked. With my droid x, I can be getting a little artsy and focus on an object with the crosshair but it'll take me 20 tries to get it to lock on, its insane, I know I'm not getting too close to my subject because it will definitely eventually focus on that object if I try over and over and over again. It's not just close ups that I find myself and my buddy with this issue either. macro shooting mode does not help. My buddie's droid X has the same exact behaviors. Eris and incredible just LOCKED ON first try with even very low contrast / detail subjects, on top of that, have a ton better camera GUI when it comes to "click to focus". I know this thing ain't no SLR but, blows me away of how terrible the camera performance is vs. the HTC android based devices. Ihink motorola will fix this? I know this thing ain't no SLR but it just blows me away how the HTC android devices camera performance (except for video) blows the Droid X away.

I cannot figure out how to attach a listener to the children elements so that I can trigger some action when the user taps on the phone number.
Is there a way to get all the children views of a layout, from the Java code so that I can loop through them and set an attribute? Specifically, I'd like to set the "layout_width" based on the screen size. Since this "layout_width" would be the same for all the views, I'd prefer to loop through instead of calling each individual View separately by their id. The following is my main.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content">
<LinearLayout android:id="@+id/myRow1" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <TextView android:text="1" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="2" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="3" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="4" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="5" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="6" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
</LinearLayout> </LinearLayout>
I have a linear layout that I have overridden because I want to > dynamically add other views to it. I am trying to add some textviews > to it and I call addViewToLayout in the onLayout method. Can't you just add your views to the layout using addView()? I have one custom LinearLayout and this is what I do and it works fine. No need to override onLayout() or onDraw(). Maybe try that

View 4 Replies View RelatedI am developing an application that has a button whose color should change green color on focusing on the button and the color of button should change to red on clicking the button. I am using setBackgroundResource() in the onClick and onLongClick listeners. Though it changes the button color, it also changes the button shape by making it look like a rectangle.
How can this be solved?

I have a list View in my app (this is the xml layout):
CODE:.............
Each item of my list View is composed of two TextView:
CODE:..............
I'm populating my listView from an ArrayAdapter, in this way:
CODE:..............
My goal is to be able to change the text color and the backgorund of these child views whenever the parent is selected or pressed.
I'd like to add a transparent panel (relativelayout) with fill_parent in width and height.
I want to use this "glasspane" in order to block all buttons underneath. Unfortunately I cannot find the right setter / xml attribute for this.
These wont work:
.setEnabled(false); .setPressed(false); .setClickable(false); .setFocusable(false); .setSaveEnabled(false); .setSelected(false);
Maybe its better to understand if I tell you that I want to create my own dialog without extending the class Dialog.
A dialog also puts a transparent glasspane above all and absorbs all clicks underneath...
Is there any possibility to do a block of text in a justify layout?

View 1 Replies View RelatedI am trying to create a very simple application (part of my learning program), vertically oriented, with an EditText at the top that receives a URL, and two buttons side by side just below that say "Get Image" or "Get Text" depending on the URL typed in (.html vs. .png, for example). The resulting elements may be later scavanged for use in a real app. I know that ScrollView can have only one child. Conceptually, I want the rest of the screen to be a vertically oriented content region for displaying either the text (TextView) of the URL and "Get Text" was clicked or the image (ImageView) in the case where it was an image and "Get Image" was clicked. I tried to do this (pseudocode) in main.xml:
<LinearLayout> <EditText /> --where to type the URL
<Button /> --click to treat URL as text
<Button /> --click to treat URL as image
<FrameLayout> --(used to be ScrollView) <LinearLayout>
<TextView /> --content region occupied by either text
<ImageView /> --or an image (but not both)
</LinearLayout> </FrameLayout> </LinearLayout>
In order not to violate the single-child requirement. However, this doesn't work and for now I'm not finding any sample out there that clues me in to how best to accomplish this. The last complaint I got while debugging was:
Caused by: java.lang.ClassCastException: android.widget.TextView

View 3 Replies View RelatedI'm creating a custom widget that extends AdapterView. Imagine something like a ListView except that the list items can overlap each other with some transparency. Because of the overlap, I'm trying to control the layout and drawing order of the children.
My issue is that the control renders it's children, but ONLY one level deep. Each child is inflated from an XML resource that contains a FrameLayout and an ImageView. The FrameLayout draws, but the ImageView is never visible. I assume I need to call some method to tell the FrameLayout to layout or draw it's children, but I'm not sure what, why, or where. Does anyone know what I'm missing?
Here is the relevant code for my custom widget: Code...
when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);
I have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };
I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?
View 1 Replies View RelatedI have a ragged hierarchy of parents and children. In that there are some parents that have 5 children...and some parents have 0 children.
The expandableListView displays the "Expand/Collpase" icon even if there are no children.
Question-Is there a way to hide the icon for only those Parents(rows) that have no children? I still want to show the row of the Parents with no children. And allow a user to click on them. But the "Expand/Collapse" icon is confusing.
I'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...
