startActivity(intent);
}

// 调用拨号面板：
public void dial(View view) {
Intent intent = new Intent();
intent.setAction(intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:10086"));
startActivity(intent);
}

// 利用 Uri 打开浏览器、打开地图等：
public void page(View view) {
// Uri uri = Uri.parse("http://www.google.com"); // 浏览器
Uri uri = Uri.parse("geo:39.899533,116.036476"); // 打开地图定位
Intent intent = new Intent();
intent.setAction(intent.ACTION_VIEW);
intent.setData(uri);
startActivity(intent);
}

// 打开视频

Uri uri = Uri.parse("/mnt/sdcard/papa.mp4");
intent.setDataAndType(uri, "video/*");
startActivity(intent);
}

// 打开发送短信的程序
public void sms(View view) {
Intent intent = new Intent();
intent.setAction(intent.ACTION_VIEW);
intent.setType("vnd.android-dir/mms-sms");
intent.putExtra("sms_body", "短信内容");
startActivity(intent);
}

// 发送短信
public void send(View view) {
Uri uri = Uri.parse("smsto:10086");
Intent intent = new Intent();
intent.setAction(intent.ACTION_SENDTO);
intent.setData(uri);
intent.putExtra("sms_body", "短信内容");
startActivity(intent);
}

// 发送彩信 , 设备会提示选择合适的程序发送
public void sendcai(View view) {
Uri uri = Uri.parse("/mnt/sdcard/aaa.png");
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/png");
intent.putExtra("sms_body", " 内容 ");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(intent);

intent.addCategory(intent.CATEGORY_HOME);
startActivity(intent);
}

// 打开系统的图片
public void openimage(View view) {
Intent intent = new Intent();
intent.setAction(intent.ACTION_VIEW);
// 如果data和type同时存在，不要分开设置
intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/papa.jsg")),
"image/*");
/*
* intent.setData(Uri.fromFile(new File("/mnt/sdcard/papa.mp4")));
* intent.setType("video/*");
*/
startActivity(intent);
}
}
