package c.c;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;/** * Demo描述: * 调用设备上的邮件客户端发送邮件 * 在此会列出该设备上的所有邮件客户端,供用户选择 */public class MainActivity extends Activity {    private Button mButton;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();}    private void init(){    mButton=(Button) findViewById(R.id.button);    mButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {startSendEmail();}});    }    private void startSendEmail() {String address="[e-mail]";String subject="邮件的标题";String body="邮件的内容";String content = "mailto:"+address+"?subject="+subject+"&body="+body;Intent returnIt = new Intent(Intent.ACTION_SENDTO);returnIt.setData(Uri.parse(content));startActivity(Intent.createChooser(returnIt, "Send email tips"));}}
