SpannableStringBuilder实现图文混排

代码

public class MainActivity extends AppCompatActivity {
    private TextView text;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        String manager = "管";
        String content = " 哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈";
        String space = "  ";    //添加空格使各个图片标示有间隔
        float scale = getResources().getDisplayMetrics().density;
        paint.setTextSize((int) (12 * scale));

        backgroundDrawable.draw(canvas);
        canvas.drawText(msg, padding, canvas.getHeight() / 2f + (Math.abs(paint.ascent()) - paint.descent()) / 2, paint);
        SpannableStringBuilder str = new SpannableStringBuilder();

        str.append(msg);
        int start = 0;
