Provide kerning/Tracking for text in android

I am trying to increase the spacing in between two words in a text. For this I came across many sites but I found the below one with the exact information I require.

http://developer.android.com/reference/java/awt/font/TextAttribute.html

For ex开发者_如何学Goample I want to use the below given constatnt

public static final TextAttribute TRACKING 

for my text. How should I do it?

Here they have listed all the textAttributes(constants) that I can use with a text. But I don't know how to use this for my text. Can anyone help me on this.

I wrote this function:

INPUT

• LinearLayout ll :

  the Layout which will be your "TexView" (make sure its orientation is vertical)

• String text:

  the text

• Context mContext

  the context

WHAT TO DO

I commented the parts that you must edit

private void populateText(LinearLayout ll, String text , Context mContext) { 
    String [] textArray = text.split(" ");
    Display display = getWindowManager().getDefaultDisplay();
    ll.removeAllViews();
    int maxWidth = display.getWidth() - 20;

    LinearLayout.LayoutParams params; // to be used over and over
    LinearLayout newLL = new LinearLayout(mContext);
    newLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT));
    newLL.setGravity(Gravity.LEFT);
    newLL.setOrientation(LinearLayout.HORIZONTAL);

    int widthSoFar = 0;

    for (int i = 0 ; i < textArray.length ; i++ ){
        LL = new LinearLayout(mContext);
        LL.setOrientation(LinearLayout.HORIZONTAL);
        LL.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.BOTTOM);
        LL.setLayoutParams(new ListView.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

        TV = new TextView(mContext);
        TV.setText(textArray[i]);
        //TV.setTextSize(size);  <<<< SET TEXT SIZE
        TV.measure(0, 0);
        params = new LinearLayout.LayoutParams(TV.getMeasuredWidth(),
                LayoutParams.WRAP_CONTENT);
        //params.setMargins(5, 0, 5, 0);  // YOU CAN USE THIS
        LL.addView(TV, params);
        LL.measure(0, 0);
        widthSoFar += TV.getMeasuredWidth();// YOU MAY NEED TO ADD THE MARGINS
        if (widthSoFar >= maxWidth) {
            ll.addView(newLL);

            newLL = new LinearLayout(mContext);
            newLL.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            newLL.setOrientation(LinearLayout.HORIZONTAL);
            newLL.setGravity(Gravity.LEFT);
            params = new LinearLayout.LayoutParams(LL
                    .getMeasuredWidth(), LL.getMeasuredHeight());
            newLL.addView(LL, params);
            widthSoFar = LL.getMeasuredWidth();
        } else {
            newLL.addView(LL);
        }
    }
    ll.addView(newLL);
}

NOTE

I have not tested it ... I used it for more complex things and it was working
