Is there a way to appear bordered text on the TextView ?
353
To add a border to Android TextView we need to create an XML containing shape as a rectangle file under the drawable's folder and set it as background to the TextView. <stroke> tag is used to set the border width and color.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml. In the above code we have taken one text view with background as border so we need to create a file in drawable as boarder.
We use attribute android: hint= "Text will show here", so if we will set the TextView in the MainActivity.
I would suggest to extend TextView
See Android Custom Component Guide
package samples.test;
public class MyTextView extends TextView {
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTextView(Context context) {
super(context);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Rect rect = new Rect();
Paint paint = new Paint();
paint.setStyle(Paint.Style.STROKE);
paint.setColor(Color.WHITE);
paint.setStrokeWidth(3);
getLocalVisibleRect(rect);
canvas.drawRect(rect, paint);
}
}
Than use it in layout xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<samples.test.MyTextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="@string/hello" />
</LinearLayout>
Most simple way is use a 9 patch background.
<TextView android:id="@+id/txt_target"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="000000000"
android:gravity="center_vertical"
android:background="@drawable/textfield_default"
android:layout_marginRight="5dip" />
