想了解Android TextView实现图文混合编排的方法的相关内容吗，zhangphil在本文为您仔细讲解Android TextView图文混合编排的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Android,TextView图文混合编排,TextView图文混排,Android,TextView图文编排，下面大家一起来学习吧。

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;
 }
 };
}
