简单实现android的WebView

废话不多说，直接上代码

首先布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/bg_webview"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="45dp"
        android:background="@drawable/bg_home_title" >

        <TextView
            android:id="@+id/wall_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="帮助"
            android:textColor="@color/white"
            android:textSize="21sp" />
    </RelativeLayout>

    <WebView
        android:id="@+id/setting_help_content"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:background="@color/bg_webview"
        android:cacheColorHint="#00000000"
        android:fadingEdge="none"
        android:scrollbars="none" />

</LinearLayout>

然后主界面Activity：

package com.suning.mobile.epa.activity.help;

import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebSettings.LayoutAlgorithm;
import android.webkit.WebSettings.RenderPriority;

import com.suning.mobile.epa.R;
import com.suning.mobile.epa.RootActivity;

/**

 *
 * @Title:

public class SettingHelpActivity extends RootActivity
{

    private static final String SETTING_HELP_URL = "file:///android_asset/setting_help.html";

     //这个是android工程中assets中的一个html文本。。该文本为：setting_help.html

    private WebView mSettingHelpContent;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_setting_help);

        mSettingHelpContent = (WebView) findViewById(R.id.setting_help_content);

        // 设置webview 自适应屏幕
        mSettingHelpContent.getSettings().setLayoutAlgorithm(
                LayoutAlgorithm.SINGLE_COLUMN);
        // webview 背景
        mSettingHelpContent.setBackgroundColor(getResources().getColor(
                R.color.bg_webview));
        // 优先加载文字
        mSettingHelpContent.getSettings()
                .setRenderPriority(RenderPriority.HIGH);
        mSettingHelpContent.loadUrl(SETTING_HELP_URL);  //实现加载。
    }

}
