logcat 中没有错误,只是当前活动关闭并且先前的活动打开。
这是我提出蓝牙启用请求的代码:
bt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (!(bluetooth.isEnabled())) {
Log.e("blue",""+"not working");
status = "Bluetooth is not Enabled.";
Toast.makeText(AddUser.this, status, Toast.LENGTH_SHORT).show();
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, 1);
}
else
{
scand();
}
}
});
这是onactivityresult:
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
System.out.println(resultCode);
Log.e("resultblue",""+resultCode);
if (resultCode == RESULT_CANCELED) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(AddUser.this, "Error Enabling bluetooth", Toast.LENGTH_LONG).show();
}
});
} else {
scand();
}
}
可能是什么问题呢?
