在android 的editText 中插入表情，其实就是将一个自己定义好的特殊的标示使用图片进行替换：

首先你要自己定义一个类继承EditText 这个类

view plain copy to clipboard print ?

packagecom.work.down;
importandroid.content.Context;
importandroid.graphics.drawable.Drawable;
importandroid.text.Spannable;
importandroid.text.SpannableStringBuilder;
importandroid.text.style.ImageSpan;
importandroid.util.AttributeSet;
importandroid.util.Log;
importandroid.widget.EditText;
publicclassImageViewsextendsEditText{
publicImageViews(Contextcontext){
super(context);
}
publicImageViews(Contextcontext,AttributeSetattrs,intdefStyle){
super(context,attrs,defStyle);
}
publicImageViews(Contextcontext,AttributeSetattrs){
super(context,attrs);
}
publicvoidinsertIntoEdit(intid){
Log.d("wljie","===");
SpannableStringBuilderbuilder=newSpannableStringBuilder(getText().toString());
Drawabledrawable=getResources().getDrawable(id);
drawable.setBounds(0,0,drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());
ImageSpanimageSpan=newImageSpan(drawable,ImageSpan.ALIGN_BASELINE);
builder.setSpan(imageSpan,getText().length(),getText().length()+"[simle]".length(),Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
setText(builder);
}
}

package com.work.down;import android.content.Context;import android.graphics.drawable.Drawable;import android.text.Spannable;import android.text.SpannableStringBuilder;import android.text.style.ImageSpan;import android.util.AttributeSet;import android.util.Log;import android.widget.EditText;public class ImageViews extends EditText {public ImageViews(Context context) {super(context);}public ImageViews(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}public ImageViews(Context context, AttributeSet attrs) {super(context, attrs);}public void insertIntoEdit(int id){Log.d("wljie","===");SpannableStringBuilder builder = new SpannableStringBuilder(getText().toString());Drawable drawable = getResources().getDrawable(id);drawable.setBounds(0,0,drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());ImageSpan imageSpan = new ImageSpan(drawable, ImageSpan.ALIGN_BASELINE);builder.setSpan(imageSpan, getText().length(),getText().length()+"[simle]".length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);setText(builder);}}

然后在mail.xml中写入

view plain copy to clipboard print ?

<?xmlversion="1.0"encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="click"
/>
<com.energysource.szj.embeded.AdView
android:id="@+id/adview_ids"
transparent="true"
debug="true"
android:layout_width="240px"
android:layout_height="38px"
android:layout_marginLeft="0px"
android:layout_marginTop="0px"
/>
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="click" /> <com.energysource.szj.embeded.AdView android:id="@+id/adview_ids"transparent="true"debug="true"android:layout_width="240px"android:layout_height="38px"android:layout_marginLeft="0px"android:layout_marginTop="0px"/></LinearLayout>

然后才MainActivity.java中

view plain copy to clipboard print ?

ImageViewsimageViews=(ImageViews)findViewById(R.id.image_view);
Log.e("wljie",R.drawable.simle+"++++^_^");
imageViews.insertIntoEdit(R.drawable.simle);
