In android ,how to set layout_marginRight in code

below is a textview layout , and I hope to modify layout_marginRight to zero in code.

<TextView
                android:id="@+id/status1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="right"
                android:layout_marginRight="@dimen/keyguard_lockscreen_status_line_font_right_margin"
                android:singleLine="true"
                android:ellipsize="marquee"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textSize="@dimen/keyguard_lockscreen_status_line_font_size"
                android:drawablePadding="4dip"
 />

when I copy aqif code to my code as below, phone halt at power on animation. 

private void updateStatus1() {
        if (mStatus1View != null) {
            MutableInt icon = new MutableInt(0);
            CharSequence string = getPriorityTextMessage(icon);
            mStatus1View.setText(string);
            LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) mStatus1View.getLayoutParams();
            params.rightMargin = 0;
            mStatus1View.setLayoutParams(params);

            mStatus1View.setCompoundDrawablesWithIntrinsicBounds(icon.value, 0, 0, 0);
            mStatus1View.setVisibility(mShowingStatus ? View.VISIBLE : View.INVISIBLE);
        }
    }

you can do it this way.

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view.getLayoutParams();
params.rightMargin = 30;
view.setLayoutParams(params);

to set Values in dp you can do it like this.

params.rightMargin = (int) (30f * this.getResources().getDisplayMetrics().density);

and the type of params depends upon its parent, if your view parent is LinearLayout the your params must be of LinearLayout.LayoutParams type, and in case of RelativeLayout, your params must be of RelativeLayout.LayoutParams type.

try as by using ViewGroup.MarginLayoutParams.rightMargin:

TextView extView tv = (TextView)findViewById(R.id.status1);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)tv.getLayoutParams();
//params.setMargins(0, 0, 0, 0); //setMargins(int left, int top, int right, int bottom)
params.rightMargin=0; 
tv.setLayoutParams(params);
