联系泡沫的EditText联系泡沫的EditText(Contact Bubble EditText

我想在创建联系人气泡MultiAutoCompleteTextView类同它是如何在Google+应用来实现。下面是一个屏幕截图：

。

我曾试图延长DynamicDrawableSpan ，以获得在文本范围的背景spannable绘制类

public class BubbleSpan extends DynamicDrawableSpan {
  private Context c;

  public BubbleSpan(Context context) {
    super();
    c = context;
  }

  @Override
  public Drawable getDrawable() {
    Resources res = c.getResources();
    Drawable d = res.getDrawable(R.drawable.oval);
    d.setBounds(0, 0, 100, 20);
    return d;
  }
}

凡我oval.xml绘制的定义是这样：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
  <solid android:color="#352765"/>
  <padding android:left="7dp" android:top="7dp"
    android:right="7dp" android:bottom="7dp" />
  <corners android:radius="6dp" />
</shape>

在具有我Activity类MulitAutoCompleteTextView ，我设置了泡跨度，如下所示：

final Editable e = tv.getEditableText();
final SpannableStringBuilder sb = new SpannableStringBuilder();
sb.append("some sample text");
sb.setSpan(new BubbleSpan(getApplicationContext()), 0, 6, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
e.append(sb);

然而，代替显示所述字符串中的第6个字符之后的椭圆形的形状，字符是不可见的，有在后台没有可绘制的椭圆形。

如果我改变BubbleSpan的getDrawable（）方法，而不是使用一个形状绘制为.png：

public Drawable getDrawable() {
  Resources res = c.getResources();
  Drawable d = res.getDrawable(android.R.drawable.bottom_bar);
  d.setBounds(0, 0, 100, 20);
  return d;
}

然后巴纽会出现，但在字符串中是跨度一部分的字符不会显示出来。我怎样才能让这个跨度中的字符显示在前台，同时自定形状绘制被显示在背景是什么？

我试图同时使用ImageSpan除了继承DynamicDrawableSpan但没有成功。

Answer 1:

感谢@chrish所有帮助。因此，这里是我做到了：

final SpannableStringBuilder sb = new SpannableStringBuilder();
TextView tv = createContactTextView(contactName);
BitmapDrawable bd = (BitmapDrawable) convertViewToDrawable(tv);
bd.setBounds(0, 0, bd.getIntrinsicWidth(),bd.getIntrinsicHeight());

sb.append(contactName + ",");
sb.setSpan(new ImageSpan(bd), sb.length()-(contactName.length()+1), sb.length()-1,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
to_input.setText(sb);

public TextView createContactTextView(String text){
  //creating textview dynamically
  TextView tv = new TextView(this);
  tv.setText(text);
  tv.setTextSize(20);
  tv.setBackgroundResource(R.drawable.oval);
  tv.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_clear_search_api_holo_light, 0);
  return tv;
}

public static Object convertViewToDrawable(View view) {
  int spec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
  view.measure(spec, spec);
  view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
  Bitmap b = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(),
            Bitmap.Config.ARGB_8888);
  Canvas c = new Canvas(b);
  c.translate(-view.getScrollX(), -view.getScrollY());
  view.draw(c);
  view.setDrawingCacheEnabled(true);
  Bitmap cacheBmp = view.getDrawingCache();
  Bitmap viewBmp = cacheBmp.copy(Bitmap.Config.ARGB_8888, true);
  view.destroyDrawingCache();
  return new BitmapDrawable(viewBmp);

}

这是给你一个完整的解决方案

//creating textview dynamicalyy
TextView textView=new TextView(context);
textview.setText("Lauren amos");
textview.setbackgroundResource(r.color.urovalshape);
textView.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.icon_cross, 0);


BitmapDrawable dd = (BitmapDrawable) SmsUtil.getDrawableFromTExtView(textView);
edittext.settext(addSmily(dd));

//convert image to spannableString
public SpannableStringBuilder addSmily(Drawable dd) {
 dd.setBounds(0, 0, dd.getIntrinsicWidth(),dd.getIntrinsicHeight());
SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append(":-)");
builder.setSpan(new ImageSpan(dd), builder.length() - ":-)".length(),builder.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

return builder;
}

  //convert view to drawable
  public static Object getDrawableFromTExtView(View view) {

    int spec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
    view.measure(spec, spec);
    view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
    Bitmap b = Bitmap.createBitmap(view.getWidth(), view.getHeight(),
            Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);
    c.translate(-view.getScrollX(), -view.getScrollY());
    view.draw(c);
    view.setDrawingCacheEnabled(true);
    Bitmap cacheBmp = view.getDrawingCache();
    Bitmap viewBmp = cacheBmp.copy(Bitmap.Config.ARGB_8888, true);
    view.destroyDrawingCache();
    return new BitmapDrawable(viewBmp);

}

下面是完整的项目文件，如果有的话，你想用Spannble

我有一个库，做你要找的内容有：

默认或完全可定制的（你甚至可以使用自己的布局）
多行支持
点击收听

看看这里

这里的快速启动：

添加ChipView到您的布局或编程方式创建它：

<com.plumillonforge.android.chipview.ChipView
    android:id="@+id/chipview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

与扩展抽象的芯片和点击监听器（如果你想）数据的列表INIT它：

List<Chip> chipList = new ArrayList<>();
chipList.add(new Tag("Lorem"));
chipList.add(new Tag("Ipsum dolor"));
chipList.add(new Tag("Sit amet"));
chipList.add(new Tag("Consectetur"));
chipList.add(new Tag("adipiscing elit"));
ChipView chipDefault = (ChipView) findViewById(R.id.chipview);
chipDefault.setChipList(chipList);
chipDefault.setOnChipClickListener(new OnChipClickListener() {
        @Override
        public void onChipClick(Chip chip) {
            // Action here !
        }
    });

默认ChipView呈现这样的：
