Question

乳清我写下面的代码，网址是在默认浏览器中打开的，为什么它没有加载到我的应用程序中。

setContentView(R.layout.activity_main);
myWebView = (WebView) findViewById(R.id.webView);
myWebView.loadUrl("http://www.google.com");

Answer 1

尝试在WebViewClient上设置WebView：

myWebView.setWebViewClient(new WebViewClient() {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url)
    {
        view.loadUrl(url);
        return true;
    }
});
myWebView.loadUrl("http://www.google.com");

也许您想要此解决方案：

#include <stdint.h>
#include <stdio.h>

int main (void)
{
  uint8_t myarr[4]={0x11,0x12,0x33,0x1A};
  char hexstr[4][2+1] = {0};

  const char HEX [16] = "0123456789ABCDEF";
  for(size_t i=0; i<4; i++)
  {
    hexstr[i][0] =  HEX[ (myarr[i] & 0xF0) >> 4 ];
    hexstr[i][1] =  HEX[ (myarr[i] & 0x0F) ];
    puts(hexstr[i]);
  }
}

别忘了添加权限：

WebView webview = findViewById(R.id.webviewLW);
webview = new WebView(this);
webview.getSettings().setLoadsImagesAutomatically(true);
webview.getSettings().setJavaScriptEnabled(true);
webview.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

webviewLWComplience.setWebViewClient(new WebViewClient() {
        @SuppressWarnings("deprecation")
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(MainActivity.this, description, Toast.LENGTH_SHORT).show();
        }

        @TargetApi(android.os.Build.VERSION_CODES.M)
        @Override
        public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
            // Redirect to deprecated method, so you can use it in all SDK versions
            onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
        }
    });

webviewLWComplience.loadUrl(CONSTANTS.HOST_URL);
setContentView(webviewLWComplience);
