requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);//先给Activity注册界面进度条功能 setContentView(R.layout.main);//布局 setProgressBarIndeterminateVisibility(true);//在需要显示进度条的时候调用这个方法 setProgressBarIndeterminateVisibility(false);//在不需要显示进度条的时候调用这个方
这样的方式,出来的progressbar是圈圈。
这个时候就要自己去创建progressbar了。自定义一个webview,这个webview中有progressbar。
public class ProgressWebView extends WebView { private ProgressBar progressbar; public ProgressWebView(Context context, AttributeSet attrs) { super(context, attrs); progressbar = new ProgressBar(context, null, android.R.attr.progressBarStyleHorizontal); progressbar.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 3, 0, 0)); addView(progressbar); // setWebViewClient(new WebViewClient(){}); setWebChromeClient(new WebChromeClient()); } public class WebChromeClient extends android.webkit.WebChromeClient { @Override public void onProgressChanged(WebView view, int newProgress) { if (newProgress == 100) { progressbar.setVisibility(GONE); } else { if (progressbar.getVisibility() == GONE) progressbar.setVisibility(VISIBLE); progressbar.setProgress(newProgress); } super.onProgressChanged(view, newProgress); } } @Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { LayoutParams lp = (LayoutParams) progressbar.getLayoutParams(); lp.x = l; lp.y = t; progressbar.setLayoutParams(lp); super.onScrollChanged(l, t, oldl, oldt); } }
使用
public class WebActivity extends BaseActivity { private ProgressWebView webview; private String url; private String name; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_web); // 获取参数 url = getIntent().getStringExtra("url"); name = getIntent().getStringExtra("name"); //绑定控件 webview = (ProgressWebView) findViewById(R.id.webview); //设置数据 titleText.setText(name); webview.getSettings().setJavaScriptEnabled(true); webview.setDownloadListener(new DownloadListener() { @Override public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) { if (url != null && url.startsWith("http://")) startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url))); } }); webview.loadUrl(url); } }
<?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:orientation="vertical" > <com.yydcdut.webdemo.ui.ProgressWebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>
如果加载的页面有需要下载文件,需要设置setDownloadListener方法,根据项目实际需求定制。
