TextView的drawableLeft、drawableRight和drawableTop不支持让drawbleLeft与文本一起居中，设置gravity为center也无济于事，重写一下TextView即可解决。

/** * drawableLeft与文本一起居中显示 * * */ public class DrawableCenterTextView extends TextView { public DrawableCenterTextView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public DrawableCenterTextView(Context context, AttributeSet attrs) { super(context, attrs); } public DrawableCenterTextView(Context context) { super(context); } @Override PRotected void onDraw(Canvas canvas) { Drawable[] drawables = getCompoundDrawables(); if (drawables != null) { Drawable drawableLeft = drawables[0]; if (drawableLeft != null) { float textWidth = getPaint().measureText(getText().toString()); int drawablePadding = getCompoundDrawablePadding(); int drawableWidth = 0; drawableWidth = drawableLeft.getIntrinsicWidth(); float bodyWidth = textWidth + drawableWidth + drawablePadding; canvas.translate((getWidth() - bodyWidth) / 2, 0); } } super.onDraw(canvas); } }
