如何在相对布局中设置文本视图的页边距

Question

I've read a few answers about setting margins of a textview programmatically when the parent is a LinearLayout, but in my case i need to set margin of a textview in a relativelayout

here's what i tried and didn't work:

description is my textview in the following code:

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        params1.addRule(RelativeLayout.RIGHT_OF, idsArray[i]);
        params1.addRule(RelativeLayout.LEFT_OF, R.id.imageButtonCamera);
        params1.addRule(RelativeLayout.BELOW, R.id.divider);
        params1.setMargins(8, 8, 8, 8)

        description.setLayoutParams(params1);

Any hint ?

Answer 1

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,  RelativeLayout.LayoutParams.WRAP_CONTENT);

    params1.setMargins(8, 8, 8, 8);

    description.setLayoutParams(params1);

try this. as it is working now and will provide margins.

look my updated ans. from the xml the margin layout working well you can set the margin from xml. as

   <TextView
    android:id="@+id/textViewTip"
    android:textSize="12sp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/imageViewItem"
    android:layout_alignTop="@+id/imageViewItem"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="20dp"
    android:layout_marginTop="22dp"
    android:layout_marginBottom="22dp"
    android:layout_toLeftOf="@+id/imageButtonCamera"
    android:layout_toRightOf="@+id/imageViewItem"
    android:text="Changable" />

it is working and if you want to change the margins programmatically then use the following code.

    LayoutParams p=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
    TextView tv=(TextView)findViewById(R.id.textViewTip);

    p.setMargins(30, 30, 30, 30);
    tv.setLayoutParams(p);
