i am using a layout file for showing a dialog. My xml file is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" android:orientation="vertical">
<EditText android:id="#+id/dialogEditText" android:text="Enter Your Text Here" android:layout_height="wrap_content" android:layout_width="match_parent"></EditText>
<DatePicker android:id="#+id/datPicker" android:layout_height="wrap_content" android:layout_width="match_parent" ></DatePicker>
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal">
<Button android:text="Add" android:id="#+id/dialogAddBtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true"></Button>
<Button android:text="Cancel" android:id="#+id/dialogCancelBtn" android:layout_width="200px" android:layout_height="wrap_content" android:layout_centerHorizontal="true"></Button>
</LinearLayout>
</LinearLayout>
I want to do something when user clicks on "OK" or Cancel button . So i have created anonymous handlers for those button. My Coding is
LayoutInflater inflater = LayoutInflater.from(obj);
View inflatedView1= inflater.inflate(R.layout.dialog_view,null);
final Dialog d= new Dialog(obj);
final Window window= d.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
window.setTitle("Add Item");
window.setContentView(R.layout.dialog_view);
final EditText input= (EditText) inflatedView1.findViewById(R.id.dialogEditText);
Button okBtn= (Button)inflatedView1.findViewById(R.id.dialogAddBtn);
okBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Toast msg= Toast.makeText(obj.getApplicationContext(),"Hello",Toast.LENGTH_LONG);
msg.show();
}
});
Button cancelBtn= (Button) inflatedView1.findViewById(R.id.dialogCancelBtn);
cancelBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
d.dismiss();
}
});
d.show();
When i am clicking on "Ok" or "Cancel button" nothing is happening. I am not able to understand why this is happening.
Please suggest me some solution.
you are setting the event handlers on your inflated view but at the same setting the content view to your plain layout:
window.setContentView(R.layout.dialog_view);
Just change this line to
window.setContentView(inflatedView1);
Or, perhaps a better approach without using the layout inflater would be to use
d.setContentView(R.layout.dialog_view);
And then setting the event handlers via
Button okBtn = (Button) d.findViewById(R.id.dialogAddBtn);
okBtn.setOnClickListener(...

I have 2 layout files, one for main layout showing (activity_main.xml) and another is for custom dialog showing (dialog_custom.xml). The 2 files are as follows-
activity_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="fill_parent">
<Button android:id="#+id/btn_1_option"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Show Alert with 1 Button"
android:padding="10dip"
android:layout_marginTop="40dip">
</Button>
<Button android:id="#+id/btn_2_option"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Show Alert With 2 Buttons"
android:padding="10dip">
</Button>
<Button android:id="#+id/btn_3_option"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Show Alert with 3 Buttons"
android:padding="10dip">
</Button>
<Button android:id="#+id/btn_custom_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Show Alert with Custom Layout - From XML"
android:padding="10dip">
</Button>
</LinearLayout>
dialog_custom.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/dialog_info"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:background="#android:color/holo_orange_dark"
android:text="#string/dialog_text"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_below="#id/dialog_info">
<Button
android:id="#+id/dialog_cancel"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.50"
android:background="#3333"
android:text="Cancel"/>
<Button
android:id="#+id/dialog_ok"
android:layout_width="0dp"

And what I have done in the Main class is -
public class Activity_Main extends Activity
{
Context context = Activity_Main.this;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog_main);
dialog.setTitle(R.string.dialog_title);
dialog.show();
}
}
So, I get a dialog like this-
Now I want to add on click option for this CANCEL and AGREE button. But if I want, I am getting forced close. Can anyone please help me, how can I do it?
Thanks for helping.
Do it as follows :
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.layout.dialog_main);
Button btCancel = (Button) dialog.findViewById(R.id.dialog_cancel);
Button btOk = (Button) dialog.findViewById(R.id.dialog_ok);
btCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Cancel Click
}
});
btOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//OK CLICK
}
});
dialog.show();
If you want to add Buttons or any Widget (inside of the Dialog) make sure that you are finding the view with dialog.findViewById(R.id.ID_WIDGET) otherwise it will crash.
I couldn't find your click code cancel and agree, but try this:
Button cancel=(Button)dialog.findViewById(R.id.dialog_cancel);
cancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// do your work
}
});
Thanks if problem persists then post your error and click code.
You may need to add View.OnClickListener to buttons of dialog.
Button btnCancel = (Button) dialog.findViewById(R.id.dialog_cancel);
Button btnOk = (Button) dialog.findViewById(R.id.dialog_ok);
btnCancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Called on click of Cancel button
}
});
btnOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Called on click of Cancel button
}
});
dialog.show();
I am looking for an easy popupmenu I could use for phones that operate on 2.3.3 and up.
Something like this, and works differently from a ContextMenu in that it doesn't require a listview:
Try the following :
Create a file dialog.xml in your layout folder and add the following code :
<?xml version="1.0" encoding="utf-8"?>
<TextView
android:id="#+id/ErrorMsg"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="Do you want to un-install this app?" />
<LinearLayout
android:layout_below="#+id/ErrorMsgDialog"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button android:id="#+id/Cancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="15sp"
android:text="Cancel" />
<Button android:id="#+id/Ok"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="15sp"
android:text="OK" />
</LinearLayout>
and then in your class file use following code to display the dialog :
AlertDialog.Builder builder = new AlertDialog.Builder(context);
View view = LayoutInflater.from(context).inflate(
R.layout.dialog, null);
builder.setView(view);
dialog = builder.create();
dialog.setCanceledOnTouchOutside(true);
Button cancel = (Button) view.findViewById(R.id.Cancel);
cancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
Button ok = (Button) view.findViewById(R.id.Ok);
ok.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Do something here for OK action
}
});
dialog.show();
The easy way to do this is just create an AlertDialog.Builder object and configured its positive and negative buttons and then set the Title and the Messages and done. Removing the need for any layout files.
Is there any similar theme generator as HoloColors or Action Bar Style Generator which would help us change theme of Dialogs and AlertDialogs in our apps?
My app uses Holo theme and I managed to change style of views such as EditTexts and Buttons but they remain unchanged when they appear in a Dialog. I would also like to change color of the blue line under a title.
I've found a few question and answers related to this topic but they practically say it's not even possible. I cannot believe it isn't.
At least for the AlertDialog it is possible. here i posted my solution of a function which is called at some point (for example button click) in your code and creates an alert dialog own layout over your screen.. the layout is a normal layout.xml which you can define the way you want. works perfect for me!
private void showAddUserGeneratedStationDialog() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(
AmplifyActivity.this);
LayoutInflater inflater = getLayoutInflater();
//inflate your layout.xml
alertDialog
.setView(inflater.inflate(R.layout.dialog_add_station, null));
//show dialog over activity screen
final AlertDialog ad = alertDialog.show();
//put actions to your ui-elements
Button cancelBtn = (Button) ad
.findViewById(R.id.list_user_generated_cancelBU);
cancelBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ad.cancel();
}
});
Button doneBtn = (Button) ad
.findViewById(R.id.list_user_generated_doneBU);
doneBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//get sth from your layout f.e. some textInput
String stationUrl = ((TextView) ad
.findViewById(R.id.list_user_generated_stationURLInput))
.getText().toString();
// did some other things
ad.dismiss();
}
});
}
and my layout.xml
<LinearLayout

android:id="#+id/list_user_generated_addStationDialog"

The layout which i am inflating into the alertbuilder is having two button. But i am not able to set the onClickListner for that. this exception is occurring. Please see my code.
XML of the custom alertDialogue.
<?xml version="1.0" encoding="utf-8"?>

AlertDialog.Builder alert = new AlertDialog.Builder(Myclass.this);
alert.setTitle("title");
alert.setIcon(iconImage);
LayoutInflater inflater = (LayoutInflater)MyClass.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.search_dialogue, null, false);
user_input= (EditText)view.findViewById(R.id.user_text);
Button cancel = (Button) findViewById(R.id.cancel);
cancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
if(content.equals("")) {
user_input.setHint(hint);
} else {
user_input.setText(content);
}
alert.setView(view);
searchAlert = alert.create();
searchAlert.show();
You are missing view before findViewById, by excluding view you are refering to the activity..:
Button cancel = (Button) view.findViewById(R.id.cancel);
Button cancel = (Button) view.findViewById(R.id.cancel);
check here
user_input= (EditText)view.findViewById(R.id.user_text);//defined view for user_input
Button cancel = (Button) findViewById(R.id.cancel);//not defined view for button
change to
Button cancel = (Button)view. findViewById(R.id.cancel);
In my application, I have a button initially on the screen, and in onclick of the button, a popup window should open. In the popup window, I have an imagebutton, and onclick of this button, I want to start an activity. The popup window opens, but I don't understand how to handle the onclick of the imagebutton inside the popup window.
In main.xml, I have a button, and in popup_example.xml, I have an imagebutton.
My Java code is as follows:
final LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final Button b=(Button)findViewById(R.id.btn);
b.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
PopupWindow pw = new PopupWindow(inflater.inflate(R.layout.popup_example,(ViewGroup)findViewById(R.layout.main)));
pw.showAtLocation(v, Gravity.LEFT,0,0);
pw.update(8,-70,150,270);
//if onclick written here, it gives null pointer exception.
ImageButton img=(ImageButton)findViewById(R.id.home);
img.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent.....
}
});
//if onclick is written here it gives runtime exception.
});
and I have two xml layouts.........
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">
<ImageButton
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ghj" />
</LinearLayout>
popup_example.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="10dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#8E2323">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5px">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5px"
android:background="#000000">
<ImageButton android:id="#+id/home"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:src="#drawable/vitalss"
android:layout_weight="1"
android:background="#8E2323"/>
</TableLayout>
</TableLayout>
</LinearLayout>
You have to find the button into the Popup view:
View pview = inflater.inflate(R.layout.popup_example,(ViewGroup)findViewById(R.layout.main));
PopupWindow pw = new PopupWindow(pview);
pw.showAtLocation(v, Gravity.LEFT,0,0);
pw.update(8,-70,150,270);
//if onclick written here, it gives null pointer exception.
ImageButton img=(ImageButton)pview.findViewById(R.id.home);
img.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent.....
}
});
In main activity button onClick you can use:
popupWindow.getContentView().findViewById(R.id.buttonInPopup).setOnClickListener(new OnClickListener(...)
This will not give error in Inflater and work properly:
LayoutInflater layoutInflater = getLayoutInflater();
View pview = layoutInflater.inflate(R.layout.popup_example, (ViewGroup)findViewById(R.layout.main));
PopupWindow pw = new PopupWindow(pview);
pw.showAtLocation(v, Gravity.LEFT,0,0);
pw.update(8,-70,150,270);
//if onclick written here, it gives null pointer exception.
ImageButton img=(ImageButton)pview.findViewById(R.id.home);
img.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent.....
}
});
best solution :)
Pass onCclickMethod from xml
<ImageButton
android:id="#+id/save_btn"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
**android:onClick="onClick"**
android:contentDescription="#string/save"
android:src="#drawable/save" />
it wroked from me..
