Android Button with Drawable - Padding
提问by Tobias Baumeister
I want to add a Drawable Image to my Button on the left and tried the following:
我想在左侧的按钮中添加一个可绘制的图像并尝试以下操作：
button = new Button(this);
button.setWidth(screen_dimens(0.25, "w")); //25% of screen width
button.setPadding(5, 5, 0, 5);
Drawable img = getResources().getDrawable(R.drawable.image);
button.setCompoundDrawablesWithIntrinsicBounds(img, null, null, null);
But I want to have a padding on the left between the drawable and the border of the button. Unfortunately, there is none.
Any help?
但我想在可绘制对象和按钮边框之间的左侧有一个填充。不幸的是，没有。
有什么帮助吗？

This will generate text + image button ( Image on Left & Text After That )
这将生成文本 + 图像按钮（左侧图像和之后的文本）
<Button
android:gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/button2"
android:paddingLeft="20dp"
style="@style/whiteText"
android:onClick="openWhyAshoka"
android:drawableLeft="@drawable/arrow"
android:drawablePadding="50dp"
android:text="Ankit" />

You have to add the padding to you drawable, by changing the 9 slices content area or by changing your drawable padding:
您必须通过更改 9 切片内容区域或更改可绘制填充来将填充添加到可绘制对象中：
<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp" />
If you are using selector you have to add the padding rule to each one of the drawable states.
如果您使用选择器，则必须将填充规则添加到每个可绘制状态。

ImageButton button=(ImageButton)findViewById(R.id.imageButton);
button.setPadding(0,10,5,0);
button.setGravity(Gravity.RIGHT);
button.setBackground(image);
