我可以选择向用户发送电子邮件的地方,我只需要知道如何制作它以便'主题'电子邮件总是在1美元不变。并将其转移到用户无法更改主题的位置。
以下是我的EmailActivity.java
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 :"));
}
});
}
}
这是我的xml文件
