我正嘗試在同一活動中初始化/打開NFC和BT模塊。 我需要它們兩個才能繼續執行任務。2個不同活動的OnActivityResult
我明白,OnResultActivity是異步,所以我想弄清楚什麼是實現它的最好方法?
這裏的大部分代碼:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initBT();
initNFC();
Intent nextIntent;
if(SaveSharedPreference.getUserName(MainActivity.this).length() == 0)
{
nextIntent = new Intent(MainActivity.this, LoginActivity.class);
}
else
{
nextIntent = new Intent(MainActivity.this, MainMenuActivity.class);
}
startActivity(nextIntent);
finish();
}
private void initBT() {
if(BTModule.GetInstance().initBT().equals(Constants.eBluetoothStatus.BT_DISABLED)){
Intent enableBtIntent = new Intent(BTModule.GetAdapter().ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
}
private void initNFC(){
mNFCState = NFCModule.initNFC(this);
if(mNFCState == eNFCStatus.NFC_NOT_SUPPORTED){
Toast.makeText(this, "NFC is not suppoeted for this device", Toast.LENGTH_LONG).show();
}
else if(mNFCState == eNFCStatus.NFC_DISABLED){
Intent nfcIntent;
if(android.os.Build.VERSION.SDK_INT >= 16){
nfcIntent = new Intent(android.provider.Settings.ACTION_NFC_SETTINGS);
}
else{
nfcIntent = new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS);
}
startActivity(nfcIntent);
Toast.makeText(this, "Please enable NFC", Toast.LENGTH_LONG);
}
else{
Toast.makeText(this, "NFC is up and running", Toast.LENGTH_LONG).show();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == eBluetoothStatus.BT_OK.ordinal()){
Toast.makeText(this, "BT is up and running", Toast.LENGTH_LONG).show();
return;
}
}
}
由於我是新手,請隨時糾正我,如果我錯了,任何事情:)
謝謝!
