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);
        }
    }

Answer 1

你可以这样做。

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

在dp中设置值，您可以这样设置。

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

并且params的类型取决于其父级，如果您的查看父级为LinearLayout，则您的参数必须为LinearLayout.LayoutParams类型，如果是RelativeLayout，则您的参数必须为RelativeLayout.LayoutParams {{1}}类型。

尝试使用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);

在android中，如何在代码中设置layout_marginRight
