android correct padding between views programmatically

Question

I programmatically created four Textviews and added it in my Linearlayout.my linearlayout has 216dp width and TextView which I created pro-grammatically has 48 dp width and height. I want to add padding between TextView. I wrote some code but I received this result

this is a my code

 for (int i = 0; i < mDigits; i++) {
        DigitView digitView = new DigitView(getContext());

        digitView.setWidth(valueInPixels);//48dp
        digitView.setHeight(valueInPixels);//48dp
        digitView.setTextColor(Color.WHITE);
        digitView.setTextSize(mDigitTextSize);
        digitView.setGravity(Gravity.CENTER);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            digitView.setElevation(mDigitElevation);
        }

        LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        if (i > 0) {
            lp.leftMargin = 10;//problem is this line
        }
        childView.addView(digitView, lp);//childview 216dp
    }

how i can to create correct padding between views programmatically? if anyone has solution please help me thanks.

Answer 1

First add appropriate android:paddingLeft to your childview I added as below:

<LinearLayout
        android:id="@+id/childView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="5dp"
        android:background="#000"
        android:orientation="horizontal">

Then edit you code as below

for (int i = 0; i < 4; i++) {
            DigitView digitView = new DigitView(this);

            digitView.setWidth(valueInPixels);//48dp
            digitView.setHeight(valueInPixels);//48dp
            digitView.setTextColor(Color.WHITE);
            digitView.setBackgroundColor(Color.YELLOW);
            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(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
                            lp.rightMargin = 10;//problem is this line

            childView.addView(digitView, lp);//childview 216dp
        }
