Android 实现打电话和发短信

				startActivity(i);

				SmsManager sm = SmsManager.getDefault();
				String message = etSmsContent.getText().toString();
				PendingIntent sentIntent = PendingIntent.getBroadcast(
						MainActivity.this, 0, new Intent(), 0);
				// 如果字数超过70,需拆分成多条短信发送
				List<String> msgs = sm.divideMessage(message);
				for (String msg : msgs) {
					sm.sendTextMessage(phoneNo, null, msg, sentIntent, null);
					// 最后二个参数为短信已发送的广播意图,最后一个参数为短信对方已收到短信的广播意图

				// 吐司 提示信息 相当于alert,第一个参数是context Activity实现context,使用外部类
				Toast toast = Toast.makeText(MainActivity.this, "发送完成",
						Toast.LENGTH_SHORT);
				// 设置吐司 显示的位置 手机屏幕的原点是左上角
				toast.setGravity(Gravity.TOP | Gravity.RIGHT, 10, 10);
				// 布局文件layout.xml
				// toast.setView(findViewById(R.layout.activity_main));
				toast.show();

</pre><pre name="code" class="java">完成上述代码后，还需要在AndroidManifest.xml中配置打电话和发短信的权限

<span style="white-space:pre">	</span><!-- 声明打电话权限 -->
    <uses-permission android:name="android.permission.CALL_PHONE" />
<span style="white-space:pre">	</span> <!-- 声明发短信权限 -->
    <uses-permission android:name="android.permission.SEND_SMS" />

可以通过调用系统自带的短信程序发送彩信：


Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/cong.png"));
intent.putExtra("address", “13677789999”);
intent.putExtra("exit_on_sent", true);
intent.putExtra("subject", "it's subject");
intent.putExtra("sms_body", "it's content");
intent.setType(“image/jpeg”); // 视频：video/mpeg*  ,文本：text/plain
