Question

由于进度对话框，我正在泄露窗口。在完成页面加载后，已经尝试了progress.dismiss（给定答案之一）。无法弄清楚崩溃的原因：/ 如果您有任何想法，请分享。

public class Webview3 extends Activity {
private WebView webView;
ProgressDialog progressDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    setContentView(R.layout.activity_webview2);

    webView = (WebView) findViewById(R.id.webView);
    webView.setWebViewClient(new MyWebViewClient());
    webView.setBackgroundResource(R.drawable.test1);
    webView.setBackgroundColor(0x00000000);
    progressDialog = new ProgressDialog(Webview3.this);
    progressDialog.setMessage("Loading...");
    progressDialog.show();

    String url = "http://www.matrimonyphotography.com/testimonial.shtml";
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
    webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
    webView.getSettings().setBuiltInZoomControls(false);
    if (Build.VERSION.SDK_INT >= 19) {
        webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
    }
    else {
        webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
    }
    webView.loadUrl(url);
}

private class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
    @Override
    public void onPageFinished(WebView view, String url) {
        if (progressDialog.isShowing()) {
            progressDialog.dismiss();
        }
    }
}

这是我的错误日志，它告诉问题的区域是progressDialog.show（）;和progressDialog.dismiss（）;在onFinishedPage（）

Answer 1

我有一些类似的问题。我发现在某些情况下，即使显示对话框，布尔值isShowing也会返回false。尝试检查它是否为空，并在其上调用dismiss。这对我有用。

Answer 2

首次初始化

progressDialog = new ProgressDialog(Webview3.this);
    progressDialog.setMessage("Loading...");
    progressDialog.show();

然后输入以下代码

webView.setWebViewClient(new MyWebViewClient());
    webView.setBackgroundResource(R.drawable.test1);
    webView.setBackgroundColor(0x00000000);
