Android实现发送短信

默认activity代码：

package com.example.test;

import android.os.Bundle;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.telephony.SmsManager;
import android.view.Menu;
import android.view.View;
import android.view.View.OnLongClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
	Activity act = this;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// 设置无标题 、全屏
		this.requestWindowFeature(Window.FEATURE_NO_TITLE);
		this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
				WindowManager.LayoutParams.FLAG_FULLSCREEN);
		setContentView(R.layout.activity_main);

		Button bt = (Button) findViewById(R.id.button1);
		// 长按按钮发送短信
		bt.setOnLongClickListener(new OnLongClickListener() {

			public boolean onLongClick(View v) {
				
				SmsManager smsManager = SmsManager.getDefault();
				PendingIntent sentIntent = PendingIntent.getBroadcast(act, 0,
						new Intent(), 0);
				//获取edittext的内容
				String addr = ((EditText) findViewById(R.id.editText1))
						.getText().toString();
				String content = ((EditText) findViewById(R.id.editText2))
						.getText().toString();
				//发送短信
				smsManager.sendTextMessage(addr, null, content, sentIntent,
						null);
				Toast.makeText(act, "发送成功 " + addr + " " + content,
						Toast.LENGTH_LONG).show();
				return false;
			}
		});
	}

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

}

布局xml

要注意的是要再androidmanifest.xml里申请发短信的权限
