SpannableString with Image example
提问by Asahi
I am looking for an example of how to build and display Android SpannableString with ImageSpan. Something like inline display of smileys.
我正在寻找如何使用 ImageSpan 构建和显示 Android SpannableString 的示例。类似于笑脸的内联显示。
Thanks a lot.
非常感谢。

Found the following and it seems to do the job:
发现以下内容，它似乎可以完成这项工作：
public class TestActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView textView = (TextView) findViewById(R.id.textview);
SpannableString ss = new SpannableString("abc");
Drawable d = ContextCompat.getDrawable(this, R.drawable.icon32);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
ss.setSpan(span, 0, 3, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
textView.setText(ss);
}

SpannableString + ImageSpan don't work in Android API 21 & 22 (I tested in Android Studio 1.2.1.1 in emulator), but if you do this:
SpannableString + ImageSpan 在 Android API 21 和 22 中不起作用（我在模拟器中的 Android Studio 1.2.1.1 中测试过），但如果你这样做：
TextView textView = (TextView) findViewById(R.id.textview);
textView.setTransformationMethod(null);
...
textView.setText(ss);
SpannableString + ImageSpan will work.
SpannableString + ImageSpan 将起作用。
