Question

我在LinearLayout中有两个imageView，我想以编程方式设置边距，但问题是边距仅适用于一个imageView。这是我的.xml文件..，

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_margin="@dimen/ivMarginBottom"
    android:layout_height="match_parent"
    android:background="@drawable/image_round"
    android:orientation="vertical"
     >

   <ImageView
        android:id="@+id/imageOne"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="@dimen/ivMarginBottom"
        android:layout_weight="1"
        android:background="@color/black"
        android:src="@drawable/icongallery" 
        />

    <ImageView 
        android:id="@+id/imageTwo"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="@color/black"
        android:src="@drawable/icongallery" />

</LinearLayout>

这是我的.java代码..，

@Override
    public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) {
        int left_margin = progress;
        int top_margin = progress;
        int right_margin = progress;
        int bottom_margin = progress;

        MarginLayoutParams marginParams1 = new MarginLayoutParams(imageOne.getLayoutParams());
        marginParams1.setMargins(left_margin, top_margin, right_margin, bottom_margin);
        LinearLayout.LayoutParams layoutParams1 = new LinearLayout.LayoutParams(marginParams1);
        imageOne.setLayoutParams(layoutParams1);

        MarginLayoutParams marginParams2 = new MarginLayoutParams(imageTwo.getLayoutParams());
        marginParams2.setMargins(left_margin, top_margin, right_margin, bottom_margin);
        LinearLayout.LayoutParams layoutParams2 = new LinearLayout.LayoutParams(marginParams2);
        imageTwo.setLayoutParams(layoutParams2);
}

Answer 1

首先获得像这样的布局参数

LinearLayout.LayoutParams lp =
                (LinearLayout.LayoutParams) imageView.getLayoutParams();

然后设置边距

Answer 2

检查以下代码：

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    lp.setMargins(left_margin, top_margin, right_margin, bottom_margin);
    imageOne.setLayoutParams(lp);
    imageTwo.setLayoutParams(lp);

Answer 3

以下是您的解决方案：
