layoutparams

In my app there is a LinearLayout which has 0 Layout height. When I click the button this layout height should be LayoutParams.WRAP_CONTENT. This is the code I use in onclicklistner. LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); slider.setLayoutParams(lp); I want to animate this. How can I set animation to slider. If you want to implement the slider animation for your layout then see this demo .

I have a View (containing an ad) that I need to scale to fit the screen width at a certain point in time (after the ad is loaded). So I have a method setHeight(myView) that calculates the correct height for the given screen width and changes the LayoutParams of the View accordingly. The crucial part of the code is this: LayoutParams params = myView.getLayoutParams(); int width = myView.getWidth(); if (params != null && width > 0) { params.height = (int) Math.round(ratio * width); } This seems to work for the most part, but sometimes the view is not scaled. It seems to only consistenly work if

This piece of code works seems to work in android api 16 - 22 but does not work in api 23. I'm simply trying to display a popupwindow with options in it and dim the background below the popupwindow: WindowPopUp windowPopUp = new WindowPopUp(mContext, mPlaces.get(position), position, fromSearch); windowPopUp.showAtLocation(v, Gravity.CENTER, 0, 0); View parent = (View) windowPopUp.getContentView().getParent(); //dim the window in the background WindowManager wm = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE); WindowManager.LayoutParams p = (WindowManager.LayoutParams) parent

Working with the XML file was easy as I could specify the parameters as <android:layout_width="fill_parent" android:layout_height="wrap_content"> But I am confused while specifying it through code. For each view I specify the parameters using view.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT)); I see that I have an option of specifying it as relative layout, frame layout etc. As of now I am using linear layout for all views such as images, text and also gridview. Should the view parameters be defined based on the layout of the parent element

Hello I have a main screen. <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=".MainActivity" > <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/> <ImageButton android:id="@+id/imageButton1" android:layout_width="55dp" android:layout_height="50dp" android:layout_alignParentTop="true" android:layout_marginTop="10dp" android

I have an EditText , a Button and a TextView . On clicking the button, textview shows the text written in edittext. Is it possible to find the size of textview occupied depending upon text. i.e. If It has three characters " abc ", what is width now, if it has 5 characters like " abcde " , then what is the width ? Rect bounds = new Rect(); Paint textPaint = textView.getPaint(); textPaint.getTextBounds(text,0,text.length(),bounds); int height = bounds.height(); int width = bounds.width(); or textView.setText("bla"); textView.measure(0, 0); textView.getMeasuredWidth(); textView.getMeasuredHeight(

it seems that there are a lot of solutions of how to use dragging of views on android . however, they are either too slow or buggy. a known solution is to have a framelayout , and the view simply changes its layoutParams as it moves using the OnTouchListener ,as described here: http://www.anddev.org/novice-tutorials-f8/android-drag-and-drop-of-normal-views-not-bitmaps-t13404.html however, if the view is an imageView , when reaching the most right (or most bottom) side of the framelayout , the image shrinks . another possible solution is to use the canvas in order to show the dragged content ,

I've hit this from various different angles. Basically the gist is this: I've layed out a template in XML for an interface which NEEDS to be run programmatically, so it's going to be populated dynamically during the run. The problem here, is that the XML TextView has quite a few layout tweaks (which work) and are necessary. But if I actually set them in code, the TextView doesn't even show up. (The TextView, by the way, is nested inside a TableRow, thus the call to weight.) The XML template I designed first, to use as reference for the code is this, and it works just fine: <TextView android:id
