Answering my own Question after two years. In order to make Generic Adapter you need abstract methods in parent class which should be implemented by child. So GenericAdapter must be Abstract and create abstract methods for data you want to change. I have different types of ArrayList to show in Adapter only it’s model class … Read more
You can use this outside activities – all you need is to provide a Context: LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE ); Then to retrieve your different widgets, you inflate a layout: View view = inflater.inflate( R.layout.myNewInflatedLayout, null ); Button myButton = (Button) view.findViewById( R.id.myButton ); EDIT as of July 2014 Davide’s answer on how … Read more
When ur are inflating the menu call this setMenuBackground() method @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater=getMenuInflater(); inflater.inflate(R.menu.menu,menu); setMenuBackground(); return true; } and write this in the setMenuBackground() method protected void setMenuBackground(){ // Log.d(TAG, “Enterting setMenuBackGround”); getLayoutInflater().setFactory( new Factory() { public View onCreateView(String name, Context context, AttributeSet attrs) { if ( name.equalsIgnoreCase( “com.android.internal.view.menu.IconMenuItemView” ) … Read more
1: The LayoutInflater takes your layout XML-files and creates different View-objects from its contents. 2: The adapters are built to reuse Views, when a View is scrolled so that is no longer visible, it can be used for one of the new Views appearing.

The first error line gives me the hint that this is related to how you are creating your dialog – not the dialog itself. Are you creating the dialog automatically (which could mean this gets called before the views are all set up) or in response to a button click? I initially had problems with … Read more
Instead of doing convertView = infalInflater.inflate(R.layout.list_item, null); do convertView = infalInflater.inflate(R.layout.list_item, parent, false); It will inflate it with the given parent, but won’t attach it to the parent.
NOW OR NOT NOW The main difference between the “third” parameter attachToRoot being true or false is this. When you put attachToRoot true : add the child view to parent RIGHT NOW false: add the child view to parent NOT NOW. Add it later. ` When is that later? That later is when you use … Read more
One simple line in your theme 🙂 <item name=”android:actionMenuTextColor”>@color/your_color</item>
I’m not sure I have followed your question- are you trying to attach a child view to the RelativeLayout? If so you want to do something along the lines of: RelativeLayout item = (RelativeLayout)findViewById(R.id.item); View child = getLayoutInflater().inflate(R.layout.child, null); item.addView(child);
Change <view to <View, because view is not about empty view. It’s for custom view defined through class attr, like below: <view android:layout_width=”wrap_content” android:layout_height=”wrap_content” class=”com.your.package.YourCustomView” /> And you got Caused by: java.lang.NullPointerException: Attempt to invoke virtual method ‘boolean java.lang.String.equals(java.lang.Object)’ on a null object reference because of LayoutInflater tries to parse class attr: LayoutInflater source code … Read more
