如何在 GridLayout 中以编程方式设置按钮之间的间距

import androidx.appcompat.app.AppCompatActivity;


import android.os.Bundle;
import android.text.PrecomputedText;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.GridLayout;
import android.widget.GridLayout.LayoutParams;
import android.widget.LinearLayout;
import android.widget.Toast;


public class MainActivity extends AppCompatActivity {


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

        GridLayout gridLayout = (GridLayout)findViewById(R.id.tableGrid);
        gridLayout.removeAllViews();

        Button button = null;
        gridLayout.setColumnCount(3);
        gridLayout.setRowCount(5);


        FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout
                .LayoutParams.WRAP_CONTENT);
        layoutParams.leftMargin = 45;
        layoutParams.rightMargin = 45;
        layoutParams.topMargin = 45;
        layoutParams.bottomMargin = 45;

        for(int i = 0; i < 3; i++)
        {
            for (int j = 0; j < 5; j++) {
                button = new Button(this);
                button.setId((5 * i) + 1 + j);
                button.setText(String.valueOf((5 * i) + 1 + j) );

                button.setLayoutParams(layoutParams);

                gridLayout.addView(button);

                button.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        int id = v.getId();
                        Toast.makeText(MainActivity.this, "" + id, Toast.LENGTH_SHORT).show();

                    }});
            }
        }
    }
}

问题是按钮之间的距离没有增加，如何解决？
