我想显示如下文本...

I'd like to show the text like the below...

我的编码如下:

SpannableString sText = new SpannableString(text); sText.setSpan(new BackgroundColorSpan(Color.YELLOW), 0, sText.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); holder.txtText.setLineSpacing(0, 1.5f); textView.setText(sText);

推荐答案

试试这个.创建自定义 TextView 并覆盖方法 draw(Canvas canvas).

try this. Create custom TextView and override method draw(Canvas canvas).

public class BgColorTextView extends TextView { public BgColorTextView(Context context) { super(context); } public BgColorTextView(Context context, AttributeSet attrs) { super(context, attrs); } public BgColorTextView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public BgColorTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); } @Override public void draw(Canvas canvas) { int lineCount = getLayout().getLineCount(); Rect rect = new Rect(); Paint paint = new Paint(); paint.setColor(getResources().getColor(R.color.YOUR_CUSTOM_COLOR)); for (int i = 0; i < lineCount; i++) { rect.top = (getLayout().getLineTop(i)); rect.left = (int) getLayout().getLineLeft(i); rect.right = (int) getLayout().getLineRight(i); rect.bottom = (int) (getLayout().getLineBottom(i) - ((i + 1 == lineCount) ? 0 : getLayout().getSpacingAdd())); canvas.drawRect(rect, paint); } super.draw(canvas); } }
