Question

我正在开发app，你可以在那里填补你的学校（使用auth等）在对话框类中，我创建了新的Spinner + TextView。如何在MainActivity中分配它们以及如何将内容视图设置到列表的底部？我知道有一些LayoutParams的东西，但我无法理解。

如果您可以帮助我在选择后从Dialog窗口中删除项目，那就太棒了。

代码：

public class OtherSubjectsDialog extends DialogFragment implements View.OnClickListener {

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    getDialog().setTitle("Title!");
    View v = inflater.inflate(R.layout.dialog_layout, null);
    v.findViewById(R.id.btn_inf).setOnClickListener(this);
    v.findViewById(R.id.btn_phys).setOnClickListener(this);
    v.findViewById(R.id.btn_soc).setOnClickListener(this);
    v.findViewById(R.id.btn_chem).setOnClickListener(this);
    v.findViewById(R.id.btn_biol).setOnClickListener(this);
    return v;
}

@TargetApi(Build.VERSION_CODES.M)
public void onClick(View v) {
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    lp.alignWithParent = true;
    Spinner spinner = new Spinner(super.getContext());
    ArrayAdapter<?> adapter = null;
    TextView textView = new TextView(super.getContext());
    switch (v.getId()) {
        case R.id.btn_inf:
            adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.inf_groups_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            textView.setText("Группа по информатике:");
            break;
        case R.id.btn_phys:
            adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.phys_groups_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            textView.setText("Группа по физике:");
            break;
        case R.id.btn_soc:
            adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.soc_groups_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            textView.setText("Группа по обществознанию:");
            break;
        case R.id.btn_chem:
            adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.chem_groups_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            textView.setText("Группа по химии:");
            break;
        case R.id.btn_biol:
            adapter = ArrayAdapter.createFromResource(super.getContext(), R.array.biol_groups_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            textView.setText("Группа по биологии:");
            break;
    }
    spinner.setAdapter(adapter);
    super.getActivity().addContentView(textView, lp);
    super.getActivity().addContentView(spinner, lp);
    dismiss();
}

public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);
}

public void onCancel(DialogInterface dialog) {
    super.onCancel(dialog);
}

}

尝试使用旋转器位置：

super.getActivity().addContentView(textView, lp);

lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
super.getActivity().addContentView(spinner, lp);
