android editText 插入表情，或者是图片

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

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);
    }



}

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

<?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>

<?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

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