Solution 1:

As commented, please try the following (sample for adding a button inside GridViewActivity which uses layout_main.xml).

public class GridViewActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RelativeLayout layout = (RelativeLayout) findViewById(R.id.relativeLayout);
        Button btnTag = new Button(this);
        btnTag.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
        btnTag.setText("Dynamic Added Button");
        layout.addView(btnTag);
    }
}

However, you should check if it works for your project or not.

UPDATE:

row_grid.xml:

My answer in your previous question:

customGridAdapter = new CustomGridViewAdapter(mContext, R.layout.row_grid, gridArray);
