loadDataWithBaseURL(baseUrl==null/"about:blank",……),baseUrl为null或"about:blank"指定相对路径.
WebView 主要调用三个方法:LoadUrl、LoadData、LoadDataWithBaseURL.
1、LoadUrl 直接加载网页、图片并显示.(本地或是网络上的网页、图片、gif)
2、LoadData 显示文字与图片内容 (模拟器1.5、1.6)
3、LoadDataWithBase 显示文字与图片内容(支持多个模拟器版本)
public class AboutView extends Activity implements OnTouchListener, OnClickListener { private Button btnAbout; private WebView aboutBrowser; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.about); btnAbout = (Button) this.findViewById(R.id.about_button); aboutBrowser = (WebView) this.findViewById(R.id.about_webkit); btnAbout.setOnTouchListener(this); btnAbout.setOnClickListener(this); // WebSettings s = aboutBrowser.getSettings(); // s.setUseWideViewPort(true); // s.setJavaScriptEnabled(true); // s.setBlockNetworkImage(true); loadHTML(); } @Override public boolean onTouch(View v, MotionEvent event) { return false; } @Override public void onClick(View v) { if(v == btnAbout) { //这里是切换Activity //注意:每个Activity都要在AndroidManifest.xml中注册 Intent i = new Intent(); i.setClass(AboutView.this, CiHaiView.class); this.startActivity(i); AboutView.this.finish(); } } public void loadHTML() { String vStr = getText(R.string.vStr).toString(); String vNum = getText(R.string.vNum).toString(); final String htmlText = "<html>" + "<head></head>" + "<body>" + "<br/>" + "<table align=\"center\" border=\"0\" cellspacing=\"15\">" + "<tr align=\"center\"><td><img src=\"file:///android_asset/edict.png\" /></td>" + "<td>" + "<b><font size=\"5\">" + vStr +"</font></b><br/>" + vNum + "</td></tr>" + "</table>" + " " + "</body></html>"; aboutBrowser.loadDataWithBaseURL("about:blank", htmlText, "text/html", "utf-8", null); } }
