在android中,如何在代码中设置layout_marginRight

Question

下面是textview布局,我希望在代码中将layout_marginRight修改为零.

<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"
 />

当我将aqif代码复制到我的代码中时,手机会在开机动画时暂停.

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);
        }
    }

你可以这样做.

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

设置值dp可以这样做.

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

并且params的类型取决于它的父级,如果你的视图父级是LinearLayout你的params必须是LinearLayout.LayoutParams类型,并且在RelativeLayout你的情况下,你的params必须是RelativeLayout.LayoutParams类型.
