如上圖  專案中要求的顯示效果是serch圖片和EditText的文字一起在中間位置。

嘗試設定了很多EditText均不能實現滿意的效果，其中：

android:drawableLeft=""

android:drawableRight=""

public class MyEditText extends EditText {


    public MyEditText(Context context) {
        super(context);
    }

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

    public MyEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    public MyEditText(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super
 
(context, attrs, defStyleAttr, defStyleRes);
    }

    @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) / 5, 0);
            }
        }
        super.onDraw(canvas);
    }

drawableLeft
即可達到如圖效果。
另外TextView也可以用此方法實現類似效果
