I need a way of turning a TableRow into a Button in android. I have tried to set up an onCLickListener() and I have tried nesting a TableRow inside a Button but that just crashes the app.
Edit:
I deleted the android:onCLick="onClick" like you said and that got rid of the crashing but nothing happens when I click the table row.
My code:
tableRow1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent openInfoTR1 = new Intent("android.intent.action.MENU");
fromTableRow = 1;
startActivity(openInfoTR1);
System.out.println("Confirmed click");
}
});
<TableLayout
android:id="#+id/tlDisplayTable"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/trTableRow1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="100"
android:visibility="invisible"
android:clickable="true">
<TextView
android:id="#+id/tvDisplayedText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20dp"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_weight="5"/>
</TableRow>
</TableLayout>
Every element that inherits from View can have attached an OnClickListener. No need to wrap it inside a button.
However, you'll have to look at how events are propagated through your layout. E.g. if you have clickable elements within your TableRow, the click events will normally be consumed by that elements and will not reach your OnClickListener. There are different ways to intercept or modify that behaviour, but you'd have to post your code to get more specific help.
EDIT:
The exception in your app comes from the line android:onClick="onClick" in your layout file. As you set the onClick listener programmatically, you do not need this. android:onClick="onClick" is a shortcut that would expect a method void onClick(View view) directly within your Activity (not, as you have it, as part of the OnClickListener implementation).

I have 2 layouts which contain the same buttons
layout_1.xml
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/button_1"
android:text="button2"
android:background="#android:color/black"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
and
layout_2.xml
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/button_1"
android:text="button2"
android:background="#android:color/white"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Please assume these are all valid layouts etc.(I am just adding the relevant code.).
So in my fragment ,I inflate and use layout_1.xml in onCreateView.I want to toggle between the 2 scenes using button_1.
I can set the listener for button_1 in layout_1.xml during the onCreateView().
The problem is trying to set a listener on that button in the second view.i.e. the listener does not activate for the second scene(with layout_2.xml).And hence i canot toggle between the 2 scenes.Is there a way to achieve this?
It would actually appear that a proper way to do this would be to on the second scene you define an action to be performed as such:
mSecondScene.setEnterAction(new Runnable() {
#Override
public void run() {
((Button) mSecondScene.getSceneRoot().findViewById(R.id. button_1)).setOnClickListener( ... );
}
This will allow you to set your ClickListener on the View without the data binding to a generic click listener method. Then you can perform the Transition to the second scene and viola.
In general, it is not a good idea to have multiple views with the same id. This is what caused the confusion here.
Note: Below is the solution used by OP that was suitable for their specific needs:
One simple solution is to use the onClick attribute in the XML file. You can assign the same onClick method to multiple items. Like this:
And in your activity.java add this:
public void buttonClicked(View v){
Log.d("TAG","Button clicked!!"
// do stuff here
}
2nd option:
When you set a listener for one button with the id of button_1, it does not set the listener for both buttons, it only sets it for the first one. If you want to set the same listener for both, all you need to do is to assign these button different ids and then assign them the same listener.
This is what you should do:
Listener myListener = new Listener(){.. blah blah....};
((Button) findViewById(R.id.some_id)).setListerner(myListener);
((Button) findViewById(R.id.some_other_id)).setListerner(myListener);
3rd option:
findViewById(R.id.id_of_layout1).findViewById(R.id.button_1)
findViewById(R.id.id_of_layout2).findViewById(R.id.button_1)
in this case, you need add some id to your layout files, for example: layout_1.xml:
<RelativeLayout
android:id="+id/id_of_layout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/button_1"
android:text="button2"
android:background="#android:color/black"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
I have created an activity in which there is four button in center . i want that when i click on any of button then there should be open another Xml file in same. i don't want to move on another activity . i want to show on same Activity with new Xml. This new Xml hide previous one.
first xml is:-
<include
android:id="#+id/header"
layout="#layout/header"
android:layout_alignParentTop="true">
</include>
<Button
style="#style/homePageBtnStyle"
android:id="#+id/howToUse"
android:layout_centerHorizontal="true"
android:layout_marginTop="110dp"
android:text="#string/howToUse"
/>
<Button
style="#style/homePageBtnStyle"
android:id="#+id/purposeOfApp"
android:layout_alignLeft="#+id/howToUse"
android:layout_marginTop="10dp"
android:text="#string/purposeOfApp"
android:layout_below="#+id/howToUse"
/>
<Button
style="#style/homePageBtnStyle"
android:id="#+id/rateThisApp"
android:layout_alignLeft="#+id/purposeOfApp"
android:layout_marginTop="10dp"
android:text="#string/rateThisApp"
android:layout_below="#+id/purposeOfApp"
/>
and second xml is:-
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:text="#string/howtousetext"
android:id="#+id/textInstruction"
android:textColor="#color/btn_border"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:
android:background="#color/themeColor"
/>
Best thing you can do is to use ViewFlipper. You can include multiple layouts in a single ViewFlipper and you can navigate from one layout to another using showNext() and showPrevious().
And since you have only two view, this becomes very simple.
call setContentView with the second xml id again and call invalidate().
try this one:
Button button1 = (Button) this.findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Test1Activity.this.setContentView(R.layout.main2);
}});
I'm a novice on the Android platform when it cames to development. However I'm going further from basic Views and I'd like to create something like the following buttons:
This is what I want to achieve. I first tought that a Button with a custom background would have sufficed. However I don't know any way to make that small darker line with the text inside. All of the image reacts like a button and gets highlighted when you touch it.
Can you help me?
If you look at the source code for Apollo you can see ArtistsFragment is not made up of Buttons but rather an inflated RelativeLayout created by a subclass of the SimpleCursorAdapter class.
Since any view can have an OnClickListener you can make any create a layout to look however you want and still have it act like a button:
// Or load it as an item from an existing layout.
View myView = this.getLayoutInflater().inflate(R.layout.anything);
myView.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
// Do stuff.
}
});
Every segment with an image could be a Layout with the background set to the appropriate image. Then, you just put the button inside of the layout.
You have to use Framelayout or RelativeLayout. For example:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="center"
android:src="#drawable/your_drawabele" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dip"
android:layout_gravity="center_horizontal|bottom"
android:padding="12dip"
android:background="#AA000000"
android:textColor="#ffffffff"
android:text="your_text" />
</FrameLayout>
I have some odd requirement. I have some menu buttons.when i am clicking on the buttons some other 3 buttons should visible. But when the focus is moving to another menu button, this 3 buttons should hide or become invisible. i did the first requirement. But unable to do the second. I take the three buttons in a relative layout.
<RelativeLayout android:id="#+id/relativelayout_inventory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/relativelayout_menu"
android:layout_toRightOf="#id/relativelayout_checkout"
android:layout_marginTop="10px"
android:layout_marginLeft="18px"
android:visibility="invisible"
>
<Button android:id="#+id/stckupdt"
android:background="#drawable/stckupdt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
</Button>
<Button android:id="#+id/pushoffer"
android:background="#drawable/stckstatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/stckupdt"
android:layout_marginTop="10px"
>
</Button>
</RelativeLayout>
And in the java file, i write the code like below..
final Button button_inventory = (Button)findViewById(R.id.inventory);
final RelativeLayout view_inventory = (RelativeLayout)findViewById(R.id.relativelayout_inventory);
button_inventory.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
view_inventory.setVisibility(View.VISIBLE);
}
});
So you are intend to do like Windows menu? I don't know why you need to do that on a phone, but you better look at Touch Event to OnClickListener: Handling UI Events
Trying to get an onclick listener working on a linearlayout but its never called :(. Have enabled clickable and focsuable (both modes) and still cant get the click listener to respond. Platform details: Android 3.0.. Any help?? Code below
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/menu_items_button"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="vertical"
android:gravity="center_horizontal"
android:paddingTop="#dimen/gen_margin_xsmall"
android:paddingBottom="#dimen/gen_margin_xsmall"
android:background="#drawable/rule_bg_menu_button"
android:clickable="true"
android:focusableInTouchMode="true"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/menu_items"
android:tag="image"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tag="text"
android:text="#string/menu_items_icon_txt"
style="#style/textDisplay.mediumLarge"
/>
</LinearLayout>
and in the code to add the event listener
_itemsButton = (LinearLayout) menu.findViewById(R.id.menu_items_button);
final Intent itemsIntent = new Intent(this, ItemsActivity.class);
_itemsButton.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(itemsIntent); //Never called!
}
}
);
The reason I'm doing this and not using an Image button instead is because the background of the "button" is state based (gradient changes) but also the image and in order to combine to the two on click / on focus, I used a linearlayout which has an ImageView in itself.. any suggestions on why the clickListener is not working on the linearLayout?
thx
Did the click go to the ImageView instead of the LinearLayout? Try clicking in the pad area (if any) or try putting the click listenner on the ImageView1.
(adding my response as a new answer so that I can use the PRE tag.)
The easy way is to set the same click listener on the image view and the text view.
View.OnClickListener activityLauncher = new View.OnClickListener() {... }
layout.setOnClickListener(activityLauncher);
imageView.setOnClickListener(activityLauncher);
textView.imageView.setOnClickListener(activityLauncher);
The width of your LinearLayout is set to "0dip", you should see nothing on the screen.
If the width is changed to "FULL_PARENT", that works. Please check your code carefully again.
