android - 如何在代码中将 android:width 设置为 0dp？

Question

我正在尝试通过代码动态添加按钮。

但我坚持如何通过代码设置android:layout_width按钮。0dp

Answer 1

尝试这个 ：

LayoutParams lp = new LayoutParams(0, LayoutParams.WRAP_CONTENT);
myButton.setLayoutParams(lp);

进口，

import android.view.ViewGroup.LayoutParams;

谢谢

Answer 2

Your button have layoutParams. Get those params, update the width and reapply them:

ViewGroup.LayoutParams lp = (ViewGroup.LayoutParams)myButton.getLayoutParams();
lp.width = 0;
myButton.setLayoutParams(lp);
