在Onclick期間自動發送郵件到[email protected] ,,,,,

Question

我有下面的代碼，它只是打開我的gmail的郵件發送屏幕，我不想那樣。 其實我想在onClick期間發送即時郵件給郵件標識。 這可能嗎？幫助please.Thanks提前。 我是否需要添加任何權限？

package com.example.emails; 
    import android.os.Bundle; 
    import android.app.Activity; 
    import android.content.Intent; 
    import android.view.Menu; 
    import android.view.View; 
    import android.view.View.OnClickListener; 
    import android.widget.Button; 

    public class Emails extends Activity { 
     private static Button email; 
     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_emails); 

      email= (Button)findViewById(R.id.button1); 
      email.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 


       Intent email = new Intent(Intent.ACTION_SEND); 
        email.putExtra(Intent.EXTRA_EMAIL, new String[]{ "arunshankar.certify@gmail.com"}); 
        //email.putExtra(Intent.EXTRA_CC, new String[]{ to}); 
        //email.putExtra(Intent.EXTRA_BCC, new String[]{to}); 
        email.putExtra(Intent.EXTRA_SUBJECT, "new mail"); 
        email.putExtra(Intent.EXTRA_TEXT, "hello"); 

        //need this to prompts email client only 
        email.setType("message/rfc822"); 

        startActivity(Intent.createChooser(email, "Choose an Email client :")); 
      } 
     }); 
     } 


     @Override 
     public boolean onCreateOptionsMenu(Menu menu) { 
      // Inflate the menu; this adds items to the action bar if it is present. 
      getMenuInflater().inflate(R.menu.emails, menu); 
      return true; 
     } 

    } 

Answer 1

是的，有可能。但是你需要一個將發送電子郵件的服務器。設備將對此服務器執行HTTP POST請求，並傳遞參數需要發送。

Answer 2

您可以通過使用JAVA郵件API發送郵件而無需設置意圖。按照這個https://code.google.com/p/javamail-android/

Answer 3

試試這個

Intent intent = new Intent(Intent.ACTION_SEND); 
       intent.setType("plain/text"); 
       intent.putExtra(android.content.Intent.EXTRA_EMAIL, 
         new String[] { "your email" }); 
       startActivity(Intent.createChooser(intent, ""));
