Android TextView实现图文混合编排的方法

本文实例为大家分享了android textview图文混合编排的具体代码，供大家参考，具体内容如下

实现技术细节不难，两个要点：

1、html代码的混合编写。
2、重写imagegetter。

例如：

布局：

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 tools:context="zhangphil.app.mainactivity">

 <textview
 android:id="@+id/text1"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content" />

 <textview
 android:id="@+id/text2"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content" />

 <textview
 android:id="@+id/text3"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:ellipsize="end"
 android:maxlines="1" />

 <textview
 android:id="@+id/text4"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:ellipsize="end"
 android:maxlines="1" />
</linearlayout>

 java代码：

package zhangphil.app;

import android.graphics.drawable.drawable;
import android.support.v4.content.contextcompat;
import android.support.v7.app.appcompatactivity;
import android.os.bundle;
import android.text.html;
import android.widget.textview;

public class mainactivity extends appcompatactivity {

 @override
 protected void oncreate(bundle savedinstancestate) {
 super.oncreate(savedinstancestate);
 setcontentview(r.layout.activity_main);

 textview text1 = (textview) findviewbyid(r.id.text1);
 textview text2 = (textview) findviewbyid(r.id.text2);
 textview text3 = (textview) findviewbyid(r.id.text3);
 textview text4 = (textview) findviewbyid(r.id.text4);

 string s = "zhang phil @ csdn android textview图文混编";

 charsequence cs1 = html.fromhtml(stringmixwithimage1(s), imgagegetter, null);
 text1.settext(cs1);

 charsequence cs2 = html.fromhtml(stringmixwithimage2(s), imgagegetter, null);
 text2.settext(cs2);

 charsequence cs3 = html.fromhtml(stringmixwithimage3(s), imgagegetter, null);
 text3.settext(cs3);

 charsequence cs4 = html.fromhtml(stringmixwithimage4(s), imgagegetter, null);
 text4.settext(cs4);
 }

 private string stringmixwithimage1(string string) {
 return string + "1 " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " ";
 }

 private string stringmixwithimage2(string string) {
 return "2 " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + string;
 }

 private string stringmixwithimage3(string string) {
 return string + "3 " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " ";
 }

 private string stringmixwithimage4(string string) {
 return "4 " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + "<img src='" + r.mipmap.ic_launcher + "'/>" + " " + string;
 }

 private html.imagegetter imgagegetter = new html.imagegetter() {
 @override
 public drawable getdrawable(string source) {
  int id = integer.parseint(source);
  drawable d = contextcompat.getdrawable(getapplicationcontext(), id);
  d.setbounds(0, 0, d.getintrinsicwidth(), d.getintrinsicheight());
  return d;
 }
 };
}
