How to remove padding around Android CheckBox

问题

I need to put check to the right hand top corner of my imageview. But when I do this I noticed a default margin around my checkbox. Is there a way to remove this??

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" >

        <ImageView
            android:id="@+id/thumbImage"
            android:layout_width="100dp"
            android:layout_height="132dp"
            android:layout_gravity="center" />
    </FrameLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:background="#ff0000"
        android:gravity="center" >

        <CheckBox
            android:id="@+id/itemCheckBox"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentEnd="true"
            android:layout_gravity="center"
            android:button="@drawable/checkbox_background"
            android:paddingLeft="0dp"
            android:paddingTop="0dp" />

    </LinearLayout>

</RelativeLayout>

回答1:

You could use a negative margin.

android:layout_marginTop = "-5dp"
android:layout_marginRight = "-5dp"

回答2:

There's now a better way of doing this:

android:minWidth="0dp"
android:minHeight="0dp"

Thanks to @VladislavShcherbakov comment, it is:

android:paddingLeft="-5dp"
android:layout_marginStart="-5dp"
android:layout_marginLeft="-5dp"
// android:translationX="-5dp"

Why to complicate with a negative padding and all. Use the simple and straight way, give padding to the FrameLayout instead tof the top most Relative layout that would do the trick. As you have only the CheckBox in the second layout there is no need to give padding for it.

Please do let me know if you face any problems or have any further doubts
