以编程方式设置android布局权重 [英] android Layout weight programmatically

问题描述

我已经对布局xml上的layout_weight进行了硬编码.但是现在我想从Java代码中给出layout_weight和weightSum.

i have hard-coded the layout_weight on layout xml.but now i want to give the layout_weight and weightSum from java code.

我们该如何在课堂上做到这一点?

How we do that from our class?

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="25" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="5"
        android:background="#F51215"
        android:paddingLeft="5dip"
        android:text="5" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="20"
        android:background="#1AC92B"
        android:paddingLeft="5dip"
        android:text="20" />
</LinearLayout>

推荐答案

myview.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,5f));
