    public DigitView(Context context) {
        this(context, null);
    }

    public DigitView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public DigitView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

    }
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);


        // If selected draw the accent
        if (isSelected()) {
            this.setBackgroundResource(R.drawable.background_border);

        }

this is a my xml code(i added my textviews in this layout)

 <LinearLayout
        android:id="@+id/my_Container_child"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
         >
    </LinearLayout>




  for (int i = 0; i < mDigits; i++) {
        digitView= new DigitView(getContext());
        digitView.setWidth(valueInPixels);
        digitView.setHeight(valueInPixels);
        digitView.setTextColor(Color.GREEN);
        digitView.setTextSize(mDigitTextSize);
        digitView.setGravity(Gravity.CENTER);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            digitView.setElevation(mDigitElevation);
        }
        childView.addView(digitView);
    }

Whatever is the parent layout of the TextViews, you need to create the appropriate LayoutParams object for each TextView. Also, you should use layoutParams for the width and height instead of setting them directly on the view.

LinearLayout layout = (LinearLayout) findViewById(R.id.my_Container_child);
for (int i = 0; i < mDigits; i++) {
    DigitView digitView = new DigitView(getContext());
    digitView.setTextColor(Color.GREEN);
    digitView.setTextSize(mDigitTextSize);
    digitView.setGravity(Gravity.CENTER);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        digitView.setElevation(mDigitElevation);
    }

    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(valueInPixels, valueInPixels);
    if (i > 0) {
        lp.leftMargin = ...; // this adds space between this view and the previous one
    }
    layout.addView(digitView, lp);
}

EDIT

Alternatively, you can do this without the LayoutParams if you use a blank divider drawable on the LinearLayout.

in res/drawable/empty_divider.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="0dp" android:width="8dp" />
</shape>

in your layout file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:showDividers="middle"
    android:divider="@drawable/ll_divider">

    <!-- ... -->

</LinearLayout>

Did you already try this:

digitView.setPadding(...);
