Question

在android中我想在同一个on-create方法上使用多个按钮。 1st将传递给另一个活动，第二个传递给webview.1。一个工作正常但是当我点击第二个按钮时，应用程序停止工作。

SelectService.java

package qcash.bd.qcashwallet;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class SelectService extends Activity {

    Button btnrecharge;
    Button btnFundTransfer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_select_service);

        Button btnrecharge = (Button) findViewById(R.id.btnRecharge);
        Button btnFundTransfer=(Button)findViewById(R.id.btnFundTransfer);

        btnrecharge.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intentMain = new Intent(getApplicationContext(),
                        SelectOperator.class);
                startActivity(intentMain);
                Toast.makeText(getApplicationContext(), "Recharge",
                        Toast.LENGTH_SHORT).show();
            }
        });
        btnFundTransfer.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent myIntent = new Intent(SelectService.this, WebViewPtoP.class);
                startActivity(myIntent);

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

WebViewPtoP.java

package qcash.bd.qcashwallet;

import android.app.Activity;
import android.webkit.WebView;
import android.webkit.SslErrorHandler;
import android.webkit.WebViewClient;
import android.net.http.SslError;
import android.os.Bundle;


public class WebViewPtoP extends Activity {


     private WebView mWebView;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_webview_ptop);

    // *********************Webview****************************
      mWebView = (WebView) findViewById(R.id.webViewPtoP);
      mWebView.getSettings().setJavaScriptEnabled(true);
      mWebView.getSettings().setDomStorageEnabled(true);
      mWebView.loadUrl("http://27.147.128.98/bl_apps/welcome/P2P_Transfer_initiate?u_name=rocky");
     // mWebView.setWebViewClient(new WebViewClient());

       mWebView.setWebViewClient(new WebViewClient() {

           @Override
           public void onReceivedSslError (WebView view, SslErrorHandler handler, SslError error) {
               handler.proceed();
           }
       });


     }



    }

Answer 1

在您的Android清单文件中声明活动。此外，如果您没有给予Interner权限，请添加这些行。

 <uses-permission android:name="android.permission.INTERNET" />

Answer 2

请仔细阅读logcat ActivityNotFoundException：您是否已在AndroidManifest.xml中声明此活动？

将该活动声明到您的清单文件中

Answer 3

我已从清单中删除了活动，然后再次添加。这次我没有直接编写XML。相反，我转到Application > Application nodes > add，选择活动，然后浏览文件来源。

这对我有用。谢谢大家的回复。

单击按钮发送到webview
