我需要我的應用程序來測試此人是否單擊是繼續或取消停止。我有一個 AlertDialogFragment：public class FragmentConfirmarPicagem extends DialogFragment { @NonNull @Override public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()) .setTitle("Confirmar") .setMessage("Deseja mesmo picar o ponto agora?") .setPositiveButton("Sim", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }) .setNegativeButton("Cancelar", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); return builder.create(); }}然后我在 MainActivity 中有這段代碼：new FragmentConfirmarPicagem().show(getSupportFragmentManager(), "Confirmar");我知道正/負按鈕的 onClick 具有該功能，但就像在 MainActivity 中一樣，我不知道單擊的按鈕?；旧衔蚁胍氖牵?nbsp; //if clicks Sim(Yes) does the following switch (verificarPonto()) { case 1: txtHoraEntrada.setText(hora); ponto.setEntrada(picagem); return; case 2: txtHoraSaidaAlmoco.setText(hora); ponto.setSaidaAlmoco(picagem); return; case 3: txtHoraEntradaTarde.setText(hora); ponto.setEntradaTarde(picagem); return; case 4: txtHoraSaida.setText(hora); ponto.setSaida(picagem); return; }

為什么需要為 Dialog 創建一個新類？
你可以直接從你的活動中做到這一點
AlertDialog.Builder builder = new AlertDialog.Builder(thisActivity)
.setTitle("Confirmar")
.setMessage("Deseja mesmo picar o ponto agora?")
.setPositiveButton("Sim", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (verificarPonto()) {
case 1:
txtHoraEntrada.setText(hora);
ponto.setEntrada(picagem);
return;
...
}
}
})
.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.create().show();
如果由于某種原因你需要創建一個新類，你可以這樣做
public static class FragmentConfirmarPicagem extends DialogFragment {
public DialogInterface.OnClickListener listener;
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
.setTitle("Confirmar")
.setMessage("Deseja mesmo picar o ponto agora?")
.setPositiveButton("Sim", listener)
.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
return builder.create();
}
}
然后，在你的活動中
FragmentConfirmarPicagem fcp = new FragmentConfirmarPicagem();
fcp.listener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (verificarPonto()) {
case 1:
txtHoraEntrada.setText(hora);
ponto.setEntrada(picagem);
return;
...
}
}
};
fcp.show(getSupportFragmentManager(), "Confirmar");
