TimePicker、栄養のリストとボタンを備えたスピナーを備えたアクティビティがあります。ボタンを押すと、Spinner をビューに動的に追加したいと考えています。

これは私のボタンです：

<Button
    android:layout_marginTop="350dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Aggiungi un altro alimento"
    android:id="@+id/button"
    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp"
    android:onClick="addAnotherAliment"/>

そして、これは onClick イベントの後に呼び出される関連メソッドです

public void addAnotherAliment(View view) {
    Spinner alimentSpinner = new Spinner(this);
    ArrayAdapter<String> alimentAdapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_spinner_dropdown_item,
            getResources().getStringArray(R.array.aliments)
    );
    alimentSpinner.setAdapter(alimentAdapter);
    LinearLayout containerLayout = (LinearLayout) findViewById(R.id.container);
    containerLayout.addView(alimentSpinner);
}

しかし、「残念ながら、あなたのアプリは停止しました」と表示されます。どうしたの？

これはアクティビティ全体です。

public class SecondActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        populateFirstSpinner();
    }

    private void populateFirstSpinner() {
        setContentView(R.layout.activity_second);
        Spinner spinnerAliments = (Spinner) findViewById(R.id.alimenti);
        ArrayAdapter<String> spinnerCountAliments = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, getResources().getStringArray(R.array.aliments));
        spinnerAliments.setAdapter(spinnerCountAliments);
    }

    public void addAnotherAliment(View view) {
        Spinner alimentSpinner = new Spinner(this);
        ArrayAdapter<String> alimentAdapter = new ArrayAdapter<String>(
                this,
                android.R.layout.simple_spinner_dropdown_item,
                getResources().getStringArray(R.array.aliments)
        );
        alimentSpinner.setAdapter(alimentAdapter);
        LinearLayout containerLayout = (LinearLayout)findViewById(R.id.container_registration);
        containerLayout.addView(alimentSpinner);
    }


}

チェックしてください。プログラムで必要な線形またはその他のレイアウトを作成します。

public Spinner addNewSpinner(int id, String[] vals) {

    sp = new Spinner(this);
    sp.setId(id);


    adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, vals);
    adapter.setDropDownViewResource((R.layout.multiline_spinner_dropdown_item));
    sp.setAdapter(adapter);

    linearLayout.addView(sp);

    return sp;
}
