I just used created by first Dialog using DialogFragment.
Everything works great except I can't get the Dialog to wrap it's layout.
My layout has the height of all elements to wrap_content.
In MyFragmentDialog I can't even find a method that would imply that it can be used to set the height of the FragmentDialog. What am I missing? How do I make a DialogFragment fit it's content?
The DialogFrament's onCreateView method:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Set title for this dialog
getDialog().setTitle("Backup & Restore");
getDialog().setCancelable(true);
View v = inflater.inflate(R.layout.backup_restore, container, false);
TextView msg = (TextView) v.findViewById(R.id.br_label_message);
msg.setText("Backups are placed in the Downloads Directory:\n" + BACKUP_PATH.getAbsolutePath());
// TextView files_label = (TextView) v.findViewById(R.id.label_restore);
Spinner files = (Spinner) v.findViewById(R.id.br_restore_file);
if (BACKUP_PATH.exists()) {
FilenameFilter filter = new FilenameFilter() {
public boolean accept(File dir, String filename) {
File sel = new File(dir, filename);
return filename.contains(FTYPE) || sel.isDirectory();
}
};
mFileList = BACKUP_PATH.list(filter);
} else {
mFileList = new String[0];
}
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getActivity(), android.R.layout.simple_spinner_item, mFileList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
files.setAdapter(adapter);
files.setOnItemSelectedListener(this);
Button backup = (Button) v.findViewById(R.id.br_backup_btn);
Button restore = (Button) v.findViewById(R.id.br_restore_btn);
Button cancel = (Button) v.findViewById(R.id.br_cancel_btn);
backup.setOnClickListener(this);
restore.setOnClickListener(this);
cancel.setOnClickListener(this);
return v;
}
This is the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Thanks,
It turns out to be an issue with LinearLayout despite setting a height on it, in DialogFragment it seems to be taking more space than I want it to. I switched layout to be a RelativeLayout the content Dialog seems to resize to fit the content.
You can make it work with all kind of layout in adding the size of the layout in the onResume of your dialogFragment :
#Override
public void onResume()
{
super.onResume();
Window window = getDialog().getWindow();
window.setLayout(300, 300);
window.setGravity(Gravity.CENTER);
}
I took a leap into the Dialog api so I am certainly not sure but you could try to call getWindow on the dialog and then call setLayout(width, height)
getDialog().getWindow().setLayout(300,300);
I don't see the top portion of your LinearLayout tag, but I've seen cases where all that was needed was the
android:orientation="vertical"
XML attribute. It can cause a headache but is fortunately easy to fix.

I use popup menu with custom items.Problems like this
Red lines represents to default width size.
but i want custom smaller width size of items(represents red lines).
public void onClick(View v) {

popup.getMenuInflater().inflate(R.menu.poupup_menu, popup.getMenu());
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
return true;

});
popup.show();//showing popup menu
}

I need to custom popup menu
Just like you, I tried a lot to change the width of the popup menu but was unsuccessful.
Somehow, I found a solution you might be looking for.
First, instead of using popup menu, I used popup window.
Step1: Making a row layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="#android:drawable/list_selector_background"
android:orientation="vertical"
android:padding="3dp">
<TextView
android:id="#+id/ItemA"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="18dp"
android:layout_marginRight="15dp"
android:layout_marginTop="3dp"
android:text="A)"
android:textAppearance="?android:attr/textAppearanceMedium"
tools:ignore="HardcodedText" />
<TextView
android:id="#+id/ItemB"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="18dp"
android:layout_marginRight="15dp"
android:layout_marginTop="10dp"
android:text="B)"
android:textAppearance="?android:attr/textAppearanceMedium"
tools:ignore="HardcodedText" />
<TextView
android:id="#+id/ItemC"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="18dp"
android:layout_marginRight="15dp"
android:layout_marginTop="10dp"
android:text="C)"
android:textAppearance="?android:attr/textAppearanceMedium"
tools:ignore="HardcodedText" />
<TextView
android:id="#+id/ItemD"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="18dp"
android:layout_marginRight="15dp"
android:layout_marginTop="10dp"
android:text="D)"
android:textAppearance="?android:attr/textAppearanceMedium"
tools:ignore="HardcodedText" />
</LinearLayout>
Step 2: Made a method to initialize popup window:
private PopupWindow initiatePopupWindow() {
try {
mInflater = (LayoutInflater) getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = mInflater.inflate(R.layout.row, null);
//If you want to add any listeners to your textviews, these are two //textviews.
final TextView itema = (TextView) layout.findViewById(R.id.ItemA);
final TextView itemb = (TextView) layout.findViewById(R.id.ItemB);
layout.measure(View.MeasureSpec.UNSPECIFIED,
View.MeasureSpec.UNSPECIFIED);
mDropdown = new PopupWindow(layout,FrameLayout.LayoutParams.WRAP_CONTENT,
FrameLayout.LayoutParams.WRAP_CONTENT,true);
Drawable background = getResources().getDrawable(android.R.drawable.editbox_dropdown_dark_frame);
mDropdown.setBackgroundDrawable(background);
mDropdown.showAsDropDown(pop, 5, 5);
} catch (Exception e) {
e.printStackTrace();
}
return mDropdown;
}
Step 3: Simply calling it in the onCreate():
public class MainActivity extends Activity {
ImageButton red, blue;
private PopupWindow mDropdown = null;
LayoutInflater mInflater;
Button pop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pop = (Button)findViewById(R.id.button1);
pop.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
initiatePopupWindow();
}
});
}
}
Hope this helps you..If it does, accept my answer..:)

I don't think you can set layout:width in menu, so you might have to create your own view layout. This might help:

Im trying to make a grid view with ImageButtons dynamically and i have this problem.
before starting i must say I'm new with android and java development (2.5 years of Objective-c).
Ok. so im using this code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_background);
ArrayList<ImageButton> tmpStrRay = new ArrayList<ImageButton>();
Boolean load=true;
for (int i= 0;load;i++){
ImageButton iv = new ImageButton(this);
InputStream ims;
try {
ims = getAssets().open("sm_backgrounds/bgSM_"+i+".jpg");
Drawable d = Drawable.createFromStream(ims, null);
iv.setImageDrawable(d);
tmpStrRay.add(iv);
} catch (IOException e) {
load = false;
e.printStackTrace();
}
System.out.print(i);
}
GridView grid = (GridView) findViewById(R.id.gridView);
ArrayAdapter<ImageButton> adapter = new ArrayAdapter<ImageButton>(this, android.R.layout.simple_list_item_1, tmpStrRay);
grid.setAdapter(adapter);
}
and i have this XML in my layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".BackgroundSelector" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:orientation="horizontal"
android:id="#+id/topLinear">
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="close"
android:text="Close"
android:textSize="15sp" />
<Button
android:id="#+id/Button01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="showCamera"
android:text="Camera"
android:textSize="15sp" />
</LinearLayout>
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="#+id/topLinear" >
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="3" >
</GridView>
</ScrollView>
</RelativeLayout>
and I'm getting this strange result of Grid with text the normally i will say that describe the ImageButton instead of showing the button himself.
I'm sure its an easy for the most of you - but please if you have the answer i would really like to get an explanation with it.
Thanks !!!
You use ArrayAdapter adapter which takes android.R.layout.simple_list_item_1 layout (which is TextView) and fills this textView with tmpStrRay[i].toString() text.
To use something other than TextViews for the array display, for instance, ImageViews, or to have some of data besides toString() results fill the views, override getView(int, View, ViewGroup) to return the type of view you want.
i got a problem with setContentView which throws me a null pointer.
In my mainFrame i got a small SurfaceView which takes about 50% of the screen.
I wanted to implement a method which makes that SurfaceView go Full Screen if you long clicked it. I did it like this:
final FrameLayout frame = (FrameLayout) findViewById(R.id.frame_layout);
frame.setOnLongClickListener(new OnLongClickListener() {
boolean clicked = false;
#Override
public boolean onLongClick(View v) {
if (clicked){
clicked = false;
(MyActivity.this).setContentView(R.layout.main);
} else {
clicked = true;
(MyActivity.this).setContentView(R.layout.fullScreen);
}
return true;
}
});
Can someone help me how to fix this problem?

I know it looks like a FrameLayout but dont get fooled it was done by someone else and it is actually a SurfaceView.
Just change the layout parameters of the SurfaceView onLong click of frame. No need to setContentView again.
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
surfaceView.setLayoutParams(lp);
I am trying to add an edit text view dynamically to a layout from the java class. However from what I have implemented nothing changes on my action. This is what I have:
public final void onCreate(final Bundle i){
int value = 0;
isEdit = false;
try
{
super.onCreate(i);
this.setContentView(R.layout.contactedit);
ContactList.soundIndicator = 0;
etPhoneNumber = new ArrayList<EditText>();
this.etPhoneNumber.add((EditText) this.findViewById(R.id.etPhoneNumberInput));
this.addNumberBtn = (Button) this.findViewById(R.id.addNumberEditText);
addNumberBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//etPhoneNumber.add(new EditText(ContactEdit.this));
try{
LinearLayout layout = (LinearLayout) findViewById(R.id.contacteditll);
EditText temp = new EditText(ContactEdit.this);
temp.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
etPhoneNumber.add(temp);
layout.addView(temp);
}catch(Exception e){
Log.d(TAG, "Failed to create new edit text");
}
}
});
}
This is the xml:

Whenever I click on my button the action is heard but nothing is done. The layout of the page does not change even though the new edit text is in my list of edit texts and I am adding the new edit text to the layout.
Any help would be appreciated thanks.
It sure gets added but you are not seeing it cause there is no space left. Two things to test:
Place the LinearLayout inside a ScrollView.
Use the weight parameter.
Using the weight parameter:
EditText temp = new EditText(ContactEdit.this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT, 1);
temp.setLayoutParams(params);
I am using a custom Dialog that contains a text field, an image, and a button. The text can contain HTML. Sometimes the bottom of the dialog gets chopped off the bottom when the text is long enough. How can I prevent this? I want Android to determine the size of the dialog but it doesn't seem to be doing that. DO I need to size the Dialog myself in this case?
Here is the layout...
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/alert_root_incorrect"
style="#style/AlertDialogTheme"
android:background="#drawable/rounded_alert"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/rounded_alert"
>
<TableLayout
android:stretchColumns="0"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TableRow>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left"
android:textStyle="bold"
android:text="Sorry, that's wrong!"
android:textColor="#color/gray_dark" />
<ImageView
android:id="#+id/check"
android:background="#drawable/xmark"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_marginRight="10dp" />
</TableRow>
</TableLayout>
<TextView
android:id="#+id/alert_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ellipsize="none"
android:text="In fact, this is where the explanation will go. Something about how this passage related to the topic"
android:textColor="#000000" />
<Button
android:id="#+id/okay_button"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_horizontal"
android:background="#drawable/rounded_alert_button"
android:text="Okay"
android:textColor="#color/white"
android:textSize="20sp" />
</LinearLayout>
</LinearLayout>
And here is the code I am using to load it...
if ( null == layout ) {
this.layout = inflater.inflate(R.layout.alert_incorrect, (ViewGroup) findViewById(R.id.alert_root_incorrect));
}
TextView message = (TextView) layout.findViewById(R.id.alert_text);
message.setText(Html.fromHtml(card.getConclusion()));
((Button) layout.findViewById(R.id.okay_button)).setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dismissDialog(INCORRECT_DIALOG);
nextQuestion();
}
});
layout.requestLayout();
dialog = new Dialog(this, R.style.AlertDialogTheme);
dialog.setContentView(layout);
dialog.setCancelable(false);
return dialog;
And here's a snap of what I mean..
Thanks,
John
This is not perfect but I've corrected it by setting the layout of the dialog relative to the default display.
dialog = new Dialog(this, R.style.AlertDialogTheme);
dialog.setContentView(layout);
Window window = dialog.getWindow();
window.setLayout(
(int)(window.getWindowManager().getDefaultDisplay().getWidth() * .90),
(int)(window.getWindowManager().getDefaultDisplay().getHeight() * .90 ));
dialog.setCancelable(false);
Just tweak the ".90" values until it feels right.
Here is the solution:
You should add a Linearlayout at the outside of your dialog's xml file
Then set this Linearlayout's gravity as "center"
the last step is creating a LayoutParams and set it to the dialog
android.view.WindowManager.LayoutParams lp = new android.view.WindowManager.LayoutParams();
lp.width = android.view.WindowManager.LayoutParams.FILL_PARENT;
lp.height = android.view.WindowManager.LayoutParams.FILL_PARENT;
alertDialog.getWindow().setAttributes(lp);
