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;

/**

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。

}

}
