我目前正在使用具有客户端/服务器系统的游戏手柄/游戏控制器功能的android应用程序,其中客户端为android,服务器为PC中的Java桌面应用程序,并以蓝牙作为连接。到目前为止,我的应用程序只能用一根手指(按住或单击)工作,现在我正在事件保持按钮A +单击按钮B或按住按钮A +保持按钮B的情况下,用两根手指使用多点触摸。 t了解如何在android上执行操作的想法,使用mCommandService(BluetoothCommandService.valueOfButon)将事件发送给java,读入Java表示按住按钮A时单击了按钮B,并使用robot.keyPress执行值表示。
我实现了来自该博客http://luugiathuy.com/2011/02/android-java-bluetooth/的示例,用于实现android和java之间的蓝牙连接。这是我在Android上的onTouch方法
public boolean onTouch(View v, MotionEvent event) {
switch(v.getId()){
case R.id.tombolL1:
cmd = BluetoothCommandService.aksi_l1;
break;
case R.id.tombolL2:
cmd = BluetoothCommandService.aksi_l2;
break;
case R.id.tombolR1:
cmd = BluetoothCommandService.aksi_r1;
break;
case R.id.tombolR2:
cmd = BluetoothCommandService.aksi_r2;
break;
case R.id.tombolAtas:
cmd = BluetoothCommandService.arah_atas;
break;
case R.id.tombolBawah:
cmd = BluetoothCommandService.arah_bawah;
break;
case R.id.tombolKiri:
cmd = BluetoothCommandService.arah_kiri;
break;
case R.id.tombolKanan:
cmd = BluetoothCommandService.arah_kanan;
break;
case R.id.tombolSegitiga:
cmd = BluetoothCommandService.aksi_segitiga;
break;
case R.id.tombolBulat:
cmd = BluetoothCommandService.aksi_bulat;
break;
case R.id.tombolSilang:
cmd = BluetoothCommandService.aksi_silang;
break;
case R.id.tombolKotak:
cmd = BluetoothCommandService.aksi_kotak;
break;
}
switch(action){
case MotionEvent.ACTION_DOWN:
handler1.removeCallbacks(mUpdateTask);
handler1.postAtTime(mUpdateTask, 200);
break;
case MotionEvent.ACTION_UP:
handler1.removeCallbacks(mUpdateTask);
break;
}
return false;
}
private Runnable mUpdateTask = new Runnable() {
@Override
public void run() {
mCommandService.write(cmd);
handler1.postAtTime(this, SystemClock.uptimeMillis() + 100);
//handler1.postAtTime(this, 200);
}
};
还有Java中的processCommand方法
private void processCommand(int command) {
try {
Robot robot = new Robot();
int key = 0;
switch(command){
case arah_atas:
key = KeyEvent.VK_UP;
break;
case arah_bawah:
key = KeyEvent.VK_DOWN;
break;
case arah_kiri:
key = KeyEvent.VK_LEFT;
break;
case arah_kanan:
key = KeyEvent.VK_RIGHT;
break;
case aksi_segitiga:
key = KeyEvent.VK_A;
break;
case aksi_bulat:
key = KeyEvent.VK_X;
break;
case aksi_silang:
key = KeyEvent.VK_Z;
break;
case aksi_kotak:
key = KeyEvent.VK_S;
break;
case aksi_l1:
key = KeyEvent.VK_Q;
break;
case aksi_l2:
key = KeyEvent.VK_W;
break;
case aksi_r1:
key = KeyEvent.VK_R;
break;
case aksi_r2:
key = KeyEvent.VK_E;
break;
case aksi_select:
key = KeyEvent.VK_SPACE;
break;
case aksi_start:
key = KeyEvent.VK_M;
break;
}
robot.keyPress(key);
Thread.sleep(50);
robot.keyRelease(key);
} catch (Exception e) {
e.printStackTrace();
}
}
请让我知道我该怎么做?
最佳答案
作为精通Android中的多点触控的人,我建议使用此this库。它抽象了处理多点触控的烦恼的烦恼。您可以缩放,旋转等。它为多点触控有问题的手机提供支持,并提供一些演示项目。而且(您之前已经做过),您可以提取转换矩阵并将此信息存储在数据库中,然后将其重新应用于图形,以便正确初始化它们。
