用androidstudio写一段实现收发信息的代码

好的，以下是用 Android Studio 实现收发信息的代码:

发送信息：

String message = "Hello World!";
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, "Send message"));

接收信息：

public void onResume() {
    super.onResume();
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("android.intent.action.SEND");
    intentFilter.addDataScheme("sms");
    registerReceiver(myReceiver, intentFilter);
}

private BroadcastReceiver myReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Do something with the received message
        String message = intent.getStringExtra(Intent.EXTRA_TEXT);
        Log.d(TAG, "Received message: " + message);
    }
};

@Override
public void onPause() {
    super.onPause();
    unregisterReceiver(myReceiver);
}

希望代码可以帮到您。
