如何在微调器中自定义对话框大小

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class CustomSizeDialog extends Dialog {

    private Spinner spinner;

    public CustomSizeDialog(Context context) {
        super(context);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.custom_dialog_layout);

        spinner = findViewById(R.id.spinner);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getContext(),
                R.array.spinner_items, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

        // 设置对话框大小
        ViewGroup.LayoutParams params = getWindow().getAttributes();
        params.width = ViewGroup.LayoutParams.MATCH_PARENT;
        params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
        getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
    }
}
