Android 将图像url加载到webview

我正试图从将图像加载到webview中，但它似乎在android 4.3上不起作用。有人能解释一下为什么我能解决这个问题吗？ 它适用于Android 4.4和Android 5，但不适用于4.3

这是我的密码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    loadUrlInWebView("http://loremflickr.com/320/240/dog");
}
private void loadUrlInWebView(String _URL) {
    WebView mWebView = (WebView) findViewById(R.id.webviewer);
    mWebView.setBackgroundColor(Color.TRANSPARENT);
    mWebView.setVerticalScrollBarEnabled(false);
    mWebView.setHorizontalScrollBarEnabled(false);
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient());
    mWebView.setWebViewClient(new MyWebViewClient());
    mWebView.loadUrl(_URL);
}

private class MyWebViewClient extends WebViewClient {

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Log.e("TAG", "error code " + errorCode);
    }
}

您可以尝试以下方法：

WebView mWebView = (WebView) findViewById(R.id.webviewer);
mWebView.loadUrl("http://loremflickr.com/320/240/dog");

只需按此加载图像，它肯定会工作。

您的错误是什么： 不要使用

loadUrlInWebView("http://loremflickr.com/320/240/dog");

使用

最后

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    loadUrlInWebView();
}
private void loadUrlInWebView() {
    WebView mWebView = (WebView) findViewById(R.id.webviewer);
    mWebView.loadUrl("http://loremflickr.com/320/240/dog");
    mWebView.setBackgroundColor(Color.TRANSPARENT);
    mWebView.setVerticalScrollBarEnabled(false);
    mWebView.setHorizontalScrollBarEnabled(false);
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient());
    mWebView.setWebViewClient(new MyWebViewClient());
    mWebView.getSettings().setUseWideViewPort (true);

}

private class MyWebViewClient extends WebViewClient {

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Log.e("TAG", "error code " + errorCode);
    }
}

我试过了，但没用检查我编辑的答案在19台设备下出现同样的错误。白色屏幕。看看这里@salahhammuda你能发布日志吗please@SalahHammouda我看着。Wait@SalahHammouda这不是你的编码错误。它与admob有关。19岁以下的api会遭受这种情况

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    loadUrlInWebView();
}
private void loadUrlInWebView() {
    WebView mWebView = (WebView) findViewById(R.id.webviewer);
    mWebView.loadUrl("http://loremflickr.com/320/240/dog");
    mWebView.setBackgroundColor(Color.TRANSPARENT);
    mWebView.setVerticalScrollBarEnabled(false);
    mWebView.setHorizontalScrollBarEnabled(false);
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient());
    mWebView.setWebViewClient(new MyWebViewClient());
    mWebView.getSettings().setUseWideViewPort (true);

}

private class MyWebViewClient extends WebViewClient {

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Log.e("TAG", "error code " + errorCode);
    }
}
