这个功能对于展示app的使用帮助是很有帮助的
核心代码:
private void initView() {
mWebView = (WebView) findViewById(R.id.load_webView);
mProgressBar = (ProgressBar) findViewById(R.id.load_progressBar);
mLoadingLayout = (RelativeLayout) findViewById(R.id.loading_layout);
mPrompt = (TextView) findViewById(R.id.prompt);
mNoInternetImageView = (ImageView) findViewById(R.id.no_internet_img);
WebSettings webSettings = mWebView.getSettings();
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
webSettings.setJavaScriptEnabled(true);
webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setUseWideViewPort(true);
// webSettings.setBuiltInZoomControls(true);
mWebView.requestFocus();
mWebView.loadUrl("file:///android_asset/software_licenses.html");
initWebViewListener();
}
private void initWebViewListener() {
// this.mWebView.setWebViewClient(new WebViewClient() {
// });
this.mWebView.setWebChromeClient(new WebChromeClient() {
@Override
public void onProgressChanged(WebView view, int newProgress) {
if (newProgress >= 80) {
mWebView.setVisibility(View.VISIBLE);
}
}
});
