Spinner and its settings

Spinner is quite a handy widget when you have a set of options to select from.

In the layout file, add the spinner widget with its width and height. Dropdown items of spinner can be taken from an array.


Use an array adapter to attach these values to the spinner.


ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
              this, R.array.lorem, android.R.layout.simple_spinner_item);
myspinner.setAdapter(adapter);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);


But I faced a  problem that text color and gravity for spinner. Text color was  black and gravity was left even after setting proper values in xml file.

Now I created a theme in /res/values/styles.xml file as follows

<style parent="@android:style/Theme" name="my_theme">
 <item name="android:textColor">@android:color/white</item> 
<item name="android:gravity">center_horizontal</item> 
</style>

 And then applied this theme to the activity in AndroidManifest,xml file of the application as

<activity android:name=".myactivity"   android:theme="@style/my_theme" />

 Good. Now my spinner was looking nice with a background, an arrow, white text which is centered.

 But the theme made the background and text both white, for dropdown items of the spinner



I created an xml file, language_options.xml  for the textview as follows

<?xml version="1.0" encoding="UTF-8"?>
<TextView 
xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="20dp" 
android:gravity="left" 
android:textColor="@android:color/black" android:layout_height="wrap_content" android:layout_width="fill_parent" 
android:id="@+id/tv" > </TextView>



 Then changed this for dropdownviewresource.

adapter.setDropDownViewResource(R.layout.language_options);

This textview is used for each of dropdown items in the pop up screen for spinner.

Next to add a title to the pop up screen I added this line


spInputLanguage.setPrompt("Select One");


Now this is how spinner items look like

Copy to clipboard

In my upcoming app, I have codes which I display. These are some times lengthy, and I want the app to be able to copy this to clipboard. Once it is in clipboard, users can paste it anywhere. So how do you copy some text from your app to clipboard. You need to use clipboard manager. Clipboard Manager This class sets and gets data for the clipboard using Clipdata objects.  You can get the object of this class using system service.  - using statement context.getSystemService(Context.CLIPBOARD_SERVICE) Example I have a dummy project with a button, onclick of which copies content to clipboard. Here is my activity file package com . hegdeapps . testapp ; import android.content.ClipData ; import android.content.ClipboardManager ; import android.support.v7.app.AppCompatActivity ; import android.os.Bundle ; import android.view.View ; import android.widget.Button ; import android.widget.TextView ; public class MainActivity extends ...

Using a list fragment with cursor adapter

All these days, I avoided using fragments. But then I realized for my this particular applications fragments are ideal. I have a master - detail list in my app. Let us say you want to have two fragments - one is a fragment which contains a list of elements and second one expands one element of the list. Both of them share the same cursor from the activity. Let us start with list fragment. Do not try creating list fragment using a wizard. It unnecearrily adds too many methods and classes. Let us start writing our own fragment like this class MyListFragment extends ListFragment { } Next using code menu override option, override the following method onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) This method should be used for inflating the layout file for the fragment.  I have a framelayout in parent activity of this fragment with the id as container. So I will specify that for inflating. The framelayout will be the paren...
