使用WebView加载HTML资源
最近的项目需要做一个如同微信中的腾讯新闻的功能，如下图所示：
直接上关键代码：
布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/contact_bg_gray"
android:orientation="vertical" >
<TextView
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_marginTop="10dip"
android:background="@drawable/big_corner_time"
android:gravity="center"
android:paddingBottom="2dip"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:paddingTop="2dip"
android:text="9:32"
android:textColor="@android:color/white"
android:textSize="18sp" />
<WebView
android:id="@+id/webView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/time"
android:layout_centerHorizontal="true"
android:layout_marginTop="8dip"
android:background="@color/contact_bg_gray"
android:layerType="software" />
</RelativeLayout>颜色请自行替换。
mWebView = (WebView) findViewById(R.id.webView1);
// holder.mWebView.loadUrl("http://www.baidu.com/");
WebSettings settings = mWebView.getSettings();
//
settings.setLayoutAlgorithm(LayoutAlgorithm.NARROW_COLUMNS);
settings.setAppCacheEnabled(true);
int width = FAMobileApp.getDeviceWidth() - (int) (16 * FAMobileApp.getDensity());
int scaleInPercent = width * 100 / 322;
System.out.println("scaleInPercent:"+scaleInPercent);
mWebView.setInitialScale(scaleInPercent);
mWebView.setBackgroundColor(mContext.getResources().getColor(
R.color.contact_bg_gray));
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("shouldOverrideUrlLoading:"+url);
//此处可作转向操作
view.loadUrl(url);
return true;
}
@Override
public void onLoadResource(WebView view, String url) {
System.out.println("onLoadResource:"+url);
}
@Override
public WebResourceResponse shouldInterceptRequest(WebView view,
String url) {
System.out.println("shouldInterceptRequest:"+url);
//TODO Here we can replace the url
if (url.endsWith("cj_all_picture.png")) {
// try {
// InputStream is = mContext.getResources().getAssets().open("cj_all_tab_bg.png");
// WebResourceResponse response = new WebResourceResponse("image/gif", "utf-8", is);
// return response;
// } catch (IOException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
}
return null;
}
});
load(holder.mWebView);
private void load(WebView mWebView) {
try {
String basePath = "/data/data/com.xxx.xx/test";
StringBuilder content = new StringBuilder();
String path = basePath + "cjsd.html";
fis = new FileInputStream(path);
byte[] buffer = new byte[1024];
int len = 0;
while ((len = fis.read(buffer)) != -1) {
content.append(new String(buffer, 0, len, "gbk"));
}
// System.out.println(content);
mWebView.getSettings().setDefaultTextEncodingName("utf-8");
String baseUrl = "file://" + basePath;
mWebView.loadDataWithBaseURL(baseUrl, content.toString(), "text/html", "utf-8",
null);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}使用的cjsc.html如下
