Floating Label for EditText

Because of space constraints, it is difficult to create self explanatory forms in mobile apps. Do you write a label for each field? If yes, the labels will also take half of the space in your form.

Hints solve the problem to some extent. If you add a hint for an EditText, when the field is blank, this hint is shown.


<EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/et1"

        android:hint="Name"/>

So now our hint is shown in Edit Text like this

But the moment you start entering value into the field, the hint vanishes.


To overcome this problem, support library comes to our rescue. It has a layout called TextInputLayout which places the hint as a floating label.

To use this first you need to add two lines to your build.gradle file in yourapplication/app directory.


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:appcompat-v7:25.1.1'
    compile 'com.android.support:design:25.1.0'
     
}

Next you should wrap your EditText in TextInputLayout as shown below. 


<android.support.design.widget.TextInputLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content">
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/et1"
        android:hint="Name"/>
   </android.support.design.widget.TextInputLayout>

Aha! Now your hint acts as a label for input field. And it is always present. When field is empty, hint is shown inside the field. When you start typing, hint is shown as floating label in accent color. And after you finish typing, hint is shown as floating label in grey color.


So you achieved all these just by using xml files (and of course support library). Happy coding!!

You can find app folder of the application here

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...
