Android TextView图文混合编排
来源:互联网 发布:cf提示客户端数据异常 编辑:程序博客网 时间:2024/09/21 09:02
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;
- }
- };
- }
