如何使按钮打开

我有一个问题，当用户点击它时，我需要我的“发送”按钮将电子邮件发送到我的按钮。 我只是想到达哪里，当用户点击发送按钮时，该按钮已经知道我的电子邮件地址并自动发送到那里的电子邮件。

到目前为止，我在EmailActivity.java中有这个

import android.app.Activity; import android.content.ActivityNotFoundException; import android.content.ComponentName; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class EmailActivity extends Activity { Button buttonSend; EditText textTo; EditText textSubject; EditText textMessage; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.email_layout); buttonSend = (Button) findViewById(R.id.buttonSend); textTo = (EditText) findViewById(R.id.editTextTo); textSubject = (EditText) findViewById(R.id.editTextSubject); textMessage = (EditText) findViewById(R.id.editTextMessage); buttonSend.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String to = textTo.getText().toString(); String subject = textSubject.getText().toString(); String message = textMessage.getText().toString(); Intent email = new Intent(Intent.ACTION_SEND); email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to}); //email.putExtra(Intent.EXTRA_CC, new String[]{ to}); //email.putExtra(Intent.EXTRA_BCC, new String[]{to}); email.putExtra(Intent.EXTRA_SUBJECT, subject); email.putExtra(Intent.EXTRA_TEXT, message); //need this to prompts email client only email.setType("message/rfc822"); startActivity(Intent.createChooser(email, "Choose an Email client :")); } }); } 

email_layout.xml ：

Answer 1

 Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts( "mailto","[e-mail]", null)); intent.putExtra(Intent.EXTRA_SUBJECT, subject); intent.putExtra(Intent.EXTRA_TEXT, message); startActivity(Intent.createChooser(intent, "Choose an Email client :")); 

使用这个。 根据您的需要更改值
