EditView中插入图片(Button 等设置均可按这样设置)

废话少说，直接上代码。

package com.imo;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.text.Html;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.Html.ImageGetter;
import android.text.style.ImageSpan;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

public class Android_demoActivity extends Activity {
    private TextView text;
    private EditText edit;
    private ImageGetter imageGetter = new ImageGetter() {
        public Drawable getDrawable(String source) {
            int id = Integer.parseInt(source);
            Drawable d = getResources().getDrawable(id);
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
            return d;
        }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        edit = (EditText) findViewById(R.id.edit);
        text = (TextView) findViewById(R.id.text);
        insertPic2();
        text.setText(edit.getText());
        insertPic1();
    }

    public void click(View view) {
        System.out.println(edit.getText());
    }

    /**
     * 第一种插入图片方式
     */
    private void insertPic1() {
        SpannableString ss = new SpannableString("pic");
        Drawable d = getResources().getDrawable(R.drawable.icon);
        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
        ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BOTTOM);
        ss.setSpan(span, 0, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        edit.append(ss);
    }

    /**
     * 第二种插入图片方式
     */
    private void insertPic2() {
        edit.append(Html.fromHtml("<img src='" + R.drawable.icon + "'/>", imageGetter, null));
    }

}

 

布局：

    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"

    <EditText
        android:id="@+id/edit"
        android:layout_width="fill_parent"
