Android - 以编程方式定位视图 [英] Android - positioning views programmatically

问题描述

我想弄清楚如何在 android 中以编程方式定位视图.例如，我们有这个 XML 代码.

I want to figure out how to position views programmatically in android. Lets say for example we have this XML code.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" 
android:id="@+id/mainLayout">
<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="121dp"
    android:layout_marginTop="140dp"
    android:text="Results" /></RelativeLayout>

如何在 android 中以编程方式实现此布局?因为我想要我的文本视图的随机位置.
