Android – How to hide underbar in EditText

androidandroid-edittexttextview

How can I hide the EditText underbar (the prompt line with little serifs at the ends)?

There might be a better way to do what I want: I have a layout with an EditText. Normally, this displays fine where the user can tap on it and begin entering or editing text.

Sometimes, however, I would like to use the same layout (simplifies other logic) to display the same data in a read-only manner. I want the presentation to be similar – it should have the same height and same font, but not have the underbar.

As a stop-gap measure, I'm going to implement this by removing the EditText and substituting a TextView. I think that will give the desired results, but it seems like a roundabout an expensive way to do something that ought to be easy to do by changing attributes.

You can set the EditText to have a custom transparent drawable or just use

android:background="@android:color/transparent"

android:background="@null"

or Programmatically

editText.setBackgroundResource(android.R.color.transparent);

Android – How to save an activity state using the save instance state

You need to override onSaveInstanceState(Bundle savedInstanceState) and write the application state values you want to change to the Bundle parameter like this:

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
  super.onSaveInstanceState(savedInstanceState);
  // Save UI state changes to the savedInstanceState.
  // This bundle will be passed to onCreate if the process is
  // killed and restarted.
  savedInstanceState.putBoolean("MyBoolean", true);
  savedInstanceState.putDouble("myDouble", 1.9);
  savedInstanceState.putInt("MyInt", 1);
  savedInstanceState.putString("MyString", "Welcome back to Android");
  // etc.
}

The Bundle is essentially a way of storing a NVP ("Name-Value Pair") map, and it will get passed in to onCreate() and also onRestoreInstanceState() where you would then extract the values from activity like this:

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
  super.onRestoreInstanceState(savedInstanceState);
  // Restore UI state from the savedInstanceState.
  // This bundle has also been passed to onCreate.
  boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
  double myDouble = savedInstanceState.getDouble("myDouble");
  int myInt = savedInstanceState.getInt("MyInt");
  String myString = savedInstanceState.getString("MyString");
}

Or from a fragment.

@Override
public void onViewStateRestored(@Nullable Bundle savedInstanceState) {
    super.onViewStateRestored(savedInstanceState);
    // Restore UI state from the savedInstanceState.
    // This bundle has also been passed to onCreate.
    boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
    double myDouble = savedInstanceState.getDouble("myDouble");
    int myInt = savedInstanceState.getInt("MyInt");
    String myString = savedInstanceState.getString("MyString");
}

You would usually use this technique to store instance values for your application (selections, unsaved text, etc.).

Android – How to center text horizontally and vertically in a TextView

I'm assuming you're using XML layout.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"
    android:text="@string/**yourtextstring**"
/>

You can also use gravity center_vertical or center_horizontal according to your need.

and as @stealthcopter commented in java: .setGravity(Gravity.CENTER);
