我正在使用这个 android 应用程序将网站转换为应用程序。基本上使用webview。到目前为止，我一切正常。唯一的问题是，如果我在应用程序内部单击，当我单击网站链接时，它会崩溃。我不知道为什么。如果我按下链接购买某样东西，我会收到一个应用程序已停止错误并且它崩溃了。
public class MainActivity extends AppCompatActivity {
WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bt = (Button)findViewById(R.id.button);
//init the webview
webView = (WebView) findViewById(R.id.webView);
//grab web settings
WebSettings webSettings= webView.getSettings();
//get web settings
webSettings.setJavaScriptEnabled(true);
//load your url
webView.loadUrl("https://gvsportscards.com/");
//for opening links inside app
webView.setWebViewClient(new WebViewClient());
bt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
webView.setVisibility(View.VISIBLE);
webView.loadUrl("https://www.youtube.com/user/GVSportsCards/featured");
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public void onBackPressed(){
if (webView.canGoBack()){
webView.goBack();
}else {
super.onBackPressed();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.play) {
webView.loadUrl("https://www.youtube.com/channel/UCDOjqC1rwUVd-qQ9ThOTuNA/live");
}
return super.onOptionsItemSelected(item);
}
}
最终目标当然是能够在应用程序上使用网站的全部功能。差不多好了！
这是错误日志

尝试使用自定义 webviewclient
public class LoginWebClient extends WebViewClient {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
}
@Override
public void onReceivedHttpError(WebView view, WebResourceRequest request,
WebResourceResponse errorResponse) {
super.onReceivedHttpError(view, request, errorResponse);
}
}
