现在,我的用户界面有 4 EditText对象。 第1行,第2行,第3行和第4行
我开始发送数据:
在第1行上,字符串为 4569
在第2行上,字符串为 369
当我尝试使用msg.getBytes().length
获取长度时,我只获得4,这是第1行的长度= 4569。但实际上,我发送了2行数据,即2 EditText(FILLED with数据)。
但是如何获得第2行,第3行和第4行的长度?
buttonConnect.setOnClickListener(将数据发送到蓝牙设备)
buttonConnect.setOnClickListener(new View.OnClickListener() {
@SuppressLint("NewApi")
@Override
public void onClick(View arg0) {
if (count == 0) {
Toast.makeText(bluetoothtest.this,
"Please enable bluetooth first.",
Toast.LENGTH_LONG).show();
}
// Need API=14
else if (!socket.isConnected()) {
Toast.makeText(bluetoothtest.this,
"Connecting! Please wait.",
Toast.LENGTH_LONG).show();
}
else {
try {
sendMessageHandle(contentRow1.getText().toString());
sendMessageHandle(contentRow2.getText().toString());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
});
sendMessageHandle方法:
private void sendMessageHandle(String msg) throws InterruptedException {
final byte ANIMATION_MODE=1;
final byte PICTURE_MODE=2;
final byte TEXT_MODE=3;
//final String PAUSE = "1";
int temp,row;
sPrefs = getSharedPreferences("storeData",MODE_PRIVATE);
byte mode = (byte) sPrefs.getInt("Mode",1);
byte [] pictureData = new byte [129];
byte [] textSetting =new byte [5];
if (socket == null) {
Toast.makeText(mContext, "No connection", Toast.LENGTH_SHORT)
.show();
return;
}
try {
OutputStream outputStream = socket.getOutputStream();
if(mode==TEXT_MODE){
int l;
textSetting[0]= 4;
Thread.sleep(500);
l = msg.getBytes().length;
System.out.println("Length is "+ l);
outputStream.write(textSetting);
outputStream.write(msg.getBytes());
}
//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//outputStream.write(PAUSE.getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
list.add(new deviceListItem(msg, false));
mAdapter.notifyDataSetChanged();
chatList.setSelection(list.size() - 1);
}
