以下のように、アクティビティ 2 にインテントを送信するアクティビティ 1 があります。
活動1
periodDatetv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(Settings.this, SettingsPeriodDate.class);
startActivityForResult(i, 100);
}
});

final Dialog dialog = new Dialog(SettingsPeriodDate.this);
dialog.setContentView(R.layout.perioddatesettings);

Toast.makeText(SettingsPeriodDate.this, "The date was saved",
Toast.LENGTH_LONG).show();
finish();
}
public void PopIt(String title, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Error");
builder.setMessage("Please check again");
builder.setCancelable(true);
final AlertDialog dlg = builder.create();
dlg.show();
final Timer t = new Timer();
t.schedule(new TimerTask() {
public void run() {
dlg.dismiss();
t.cancel();
}
}, 100000);
}
アクティビティ 1の結果は次のようになります。
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 100:
System.err.println("after intent back 111111=== ");
if (resultCode == Activity.RESULT_OK) {
System.err.println("after intent back if=== ");
int day = data.getIntExtra("Day", 0);
int month = data.getIntExtra("Month", 0);
int year = data.getIntExtra("Year", 0);
System.err.println("after intent back =///== " + day + "-" + month
+ "-" + year);
Toast.makeText(Settings.this,day+"?"+month+"?"+year,Toast.LENGTH_SHORT).show();
periodDatetv.setText(day + "/" + month + "/" + year);
break;
}
}
}
ただし、onActivityResult メソッドは実行されません。私のコードで何が間違っていますか? 教えてください..そして事前に感謝します
