Android EditView使用技巧

 EditText ed = new
 EditText(
this
);
 Editable eb = ed.getEditableText();

 //获取光标位置
 int
 position = ed.getSelectionStart();

 //指定位置插入字符
 eb.insert(position, "XXX"
);


 //插入图片
 //定义图片所占字节数（“Tag”的长度）
 SpannableString ss = new
 SpannableString(
"Tag"
);
 //定义插入图片
 Drawable drawable = getResources().getDrawable(R.drawable.icon);
 ss.setSpan(new
 ImageSpan(drawable,ImageSpan.ALIGN_BASELINE), 
0
, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 drawable.setBounds(2
, 
0
, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
 //插入图片
 eb.insert(position, ss);


 //设置可输入最大字节数
 ed.setFilters(new
 InputFilter[]{
new
 InputFilter.LengthFilter(
10
)});


 //拉起lancher桌面
 Intent i = new
 Intent(Inten.ACTION_MAIN);
i.addCategory(Inten.CATEGORT_HOME);
startActivity(i);

//去掉List拖动时的阴影
 list.setCacheColorHint(0
);
