通过改写ArrayAdapter 用AutoCompleteTextView 实现汉字和拼音双向关联

核心提示：@Overrideprotected void publishResults(CharSequence constraint, FilterResults results) {mObjects = (List) results.values;if (results.count > 0) {notifyDataSe

@Override

protected void publishResults(CharSequence constraint, FilterResults results) {

mObjects = (List) results.values;

if (results.count > 0) {

notifyDataSetChanged();

} else {

notifyDataSetInvalidated();

}

}

}

}

复制代码

调用代码如下：

cAdapter = new CityAdapter(this,android.R.layout.simple_dropdown_item_1line, 汉字数组,拼音数组);

autoView.setAdapter(cAdapter);

autoView.setThreshold(1);

//其中 autoView 为 AutoCompleteTextView
