我已经完成了使用ActionBarSherlock向我的WebView添加ProgressBar的所有必要步骤,但我没有在Android 4.0之前获得任何结果。有人可以帮忙吗?我从ABS导入了Window,添加了requestWindowFeature(Window.FEATURE_PROGRESS);在设置内容之前,我只是不知道该怎么做。请不要告诉我按照样品,因为我已经尝试过,但我没有得到任何结果。谢谢。

以下是MainActivity.class的代码

package com.twk95.webviewtest;

import android.content.Intent;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import com.actionbarsherlock.view.Window;

public class MainActivity extends SherlockActivity {

public static WebView webView;
final SherlockActivity MyActivity = this;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_PROGRESS);
    setContentView(R.layout.activity_main);
    webView = (WebView) findViewById(R.id.WebView);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebViewClient(new WebViewClient() {
        public boolean shouldOverrideUrlLoading(WebView webview, String url) {
            webview.loadUrl(url);
            return true;
        }
    });
    webView.loadUrl("http://www.google.com");
    webView.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view, int progress) {
            MyActivity.setTitle("Loading...");
            MyActivity.setProgress(progress * 100);
            setSupportProgressBarVisibility(true);

            if (progress == 100) {
                MyActivity.setTitle(R.string.app_name);
                setSupportProgressBarVisibility(false);
            }
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.webview_menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.webReload:
        webView.reload();
        break;
    case android.R.id.home:
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
        return true;
    }
    return false;
}
}

确保requestWindowFeature方法正在使用com.actionbarsherlock.app.SherlockActivity.requestWindowFeature(long featureId),然后使用setSupportProgress(int progress)进行更新,而不是使用MyActivity.setProgress()
