java - 如何在android中以编程方式删除 ImageView 周围的填充

Question

我在一排中有 4 个 ImageView ，但我想要可见，并且需要根据响应执行操作。那么如何删除我硬编码布局中未使用的空间。

<ImageView
        android:id="@+id/imgFacebookUrl"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/facebook_login_guest"
        app:layout_anchor="@id/appbar"
        android:visibility="gone"
        app:layout_anchorGravity="bottom|center" />

    <ImageView
        android:id="@+id/imgLinkdinUrl"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="200dp"
        android:src="@drawable/icon_linkdin"
        app:layout_anchor="@id/appbar"
        android:visibility="gone"
        app:layout_anchorGravity="bottom|center" />

Answer 1

public void setPadding (int left, int top, int right, int bottom)

Sets the padding. The view may add on the space required to display the scrollbars, depending on the style and visibility of the scrollbars. So the values returned from getPaddingLeft(), getPaddingTop(), getPaddingRight() and getPaddingBottom() may be different from the values set in this call.

终于

ImageView ImageViewObj = (ImageView) findViewById(R.id.imgLinkdinUrl);
ImageViewObj.setPadding(0, 0, 0, 0);
