几天前，我问了类似的问题- Android 3D按钮src填充，但是对于文本，我无法使用此技巧:/(或不知道怎么做).

Few days ago I asked similar question - Android 3D button src padding, but for text I cant use this trick :/ (or dont know how).

推荐答案

您将需要创建自定义Button并覆盖更改状态的方法，以便根据当前状态自定义重力.

You will need to create a custom Button and override the methods for changing it's state in order to customize it's gravity based on the current state.

例如，以下是自定义Button的代码，其按下时文本将跳到底部:

For example here is the code for a custom Button whose text will jump to the bottom when it is pressed:

public class VariableGravityButton extends Button {
    public VariableGravityButton(Context context) {
        super(context);
    }

    public VariableGravityButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public VariableGravityButton(Context context, AttributeSet attrs,
            int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setPressed(boolean pressed) {
        if (pressed != isPressed()) {
            setGravity(pressed ? Gravity.CENTER_HORIZONTAL |
                    Gravity.BOTTOM : Gravity.CENTER);
        }
        super.setPressed(pressed);
    }
}
