App - Dialog

Dialog

別の場所で宣言したダイアログを showDialog(ID)で表示します。 より単純に App - Activity - Dialog のような方法もあります。

ダイアログのアイコンはあらかじめ定義されている物も多々あります。 http://developer.android.com/reference/android/R.drawable.html

Java

ソースコード http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/app/AlertDialogSamples.html

//ボタンを押すとActivityのshowDialog(id)よぶようにしています。
//(内部から、onCreateDialogが呼ばれるようです)

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.alert_dialog);

        /* Display a text message with yes/no buttons and handle each message as well as the cancel action */
        Button twoButtonsTitle = (Button) findViewById(R.id.two_buttons);
        twoButtonsTitle.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                showDialog(DIALOG_YES_NO_MESSAGE);
            }
        });
...
}

//onCreateDialogを上書きしてます。

  protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DIALOG_YES_NO_MESSAGE:
         ...
    case DIALOG_YES_NO_LONG_MESSAGE:
        ...
}
