如何通過按發送按鈕在android中輸出提交的信息？

我有一個簡單的聯繫表格應用程序，我想完成的是一旦表格填寫完畢，我想要的信息發送按鈕後直接發送到我的gmail。我不想讓「完成操作」彈出。只是直接發送到我的Gmail。我目前正在使用意圖使信息被髮送。有沒有其他類型的方法可以用來將信息直接發送到我的Gmail？如何通過按發送按鈕在android中輸出提交的信息？

這裏是我的MainActivity.java文件：

package com.qnutapps.contactform1; 

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

public class MainActivity extends Activity implements OnClickListener{ 
/** Called when the activity is first created. */ 

    EditText etname, etphone, etemail, etadd; 

    Button send; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main);  

    etname = (EditText) findViewById (R.id.etName); 

    etphone = (EditText) findViewById (R.id.etPhone); 

    etemail = (EditText) findViewById (R.id.etEmail);  

    etadd = (EditText) findViewById (R.id.etAdd); 

    send = (Button) findViewById (R.id.send);  

    send.setOnClickListener(this); 
    } 

public void onClick(View Arg0) { 


     //if(etname.getText().toString().length()==0) 
     //{   
      //etname.setError("Please Enter Your Name"); 
     //} 
     //else if(etphone.getText().toString().length()==0) 
     //{   
      //etphone.setError("Please Enter Your Phone #"); 
     //} 
     //else if(etemail.getText().toString().length()==0) 
     //{   
      //etemail.setError("Please Enter Your E-mail"); 
     //} 
     //else if(etadd.getText().toString().length()==0) 
     //{   
      //etadd.setError("Vul uw bericht in"); 
     //} 
     //else if(subject.getSelectedItemPosition()==0) 
     //{   
      //Toast.makeText(MainActivity.this,"Please select the Subject",Toast.LENGTH_SHORT).show(); 
     //} 
     //else 
     //{    
      Toast.makeText(getApplicationContext(), "Sending E-Mail", Toast.LENGTH_SHORT).show(); //Sends message after button is clicked 

      StringBuilder body = new StringBuilder(); 

      body.append("Name: "+etname.getText().toString()); 

      body.append("\nPhone: "+etphone.getText().toString()); 

      body.append("\nEmail: "+etemail.getText().toString()); 

      body.append("\nAdditional Information: "+etadd.getText().toString()); 



      Intent emailIntent = new Intent(Intent.ACTION_SEND); 

      emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});   

      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Customer Details"); 

      emailIntent.putExtra(Intent.EXTRA_TEXT, body.toString()); 

      emailIntent.setType("message/rfc822"); //can also use "message/rfc822" 

      startActivity(emailIntent); 


     }   
} 
//}

看到這個http://stackoverflow.com/questions/46663/how-to-send-an-email-by-java-application-using -gmail-yahoo-hotmail –

正如@madlymad所說的，要麼使用JavaMail API直接發送消息，要麼讓Android處理請求。與'startActivity（Intent.createChooser（emailIntent，「選擇一個電子郵件客戶端：」））;'小信箱會彈出，你可以選擇你想要使用哪個電子郵件客戶端。您不應該假設您的手機上有哪些電子郵件客戶端，也不應該爲用戶做出選擇......至少這是它背後的想法。所以你需要盒子。 – GameDroids

謝謝，我會試一試 – OliverTwist
