为API 8中的RadioButtons复制android：drawableStart

Question

I need a custom radio button with a custom background, centered text, an icon immediately before the text, but without the default indicator.

Currently, I have the following code:

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:button="@null"
    android:background="@drawable/bg_rbtn_custom"
    android:drawableLeft="@drawable/icon"
    android:text="Lorem ipsum…" />

The problem is the icon defined in drawableLeft , is pushed all the way to the left, ie

[icon]____Lorem ipsum…________

I need this:

____[icon]Lorem ipsum…________

The same thing happens when I use android:button="@drawable/icon ; the icon is place at the left-most part of the View , and the text is then centred inside the left-over space (rather than being centred relative to the entire View ). I am Android API 8, so I can't use drawableStart , so I need a way to duplicate its behaviour (at least I assume that's what it does). The text is dynamic, and will change at runtime, so I can't really hard code the padding.

My question is quite similar to this one , but that guy only needed a Button , but I need a RadioButton that'll work in a RadioGroup .

First thoughts would be to try

android:paddingLeft="#db"

where "#db" would be the number of pixels it would take to center everything

After trying your code and replacing the background and icon to local resources I had, I was unable to recreate the issue you are having. Could it be possible that the icon you are using has transparent pixels on its right edge?
