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; } }; }
代码运行结果:
