问题：

不需要的填充

您可以清楚地看到按钮周围的填充

代码：

public void startGameDialog(){

    Context context = GameBoardActivity.this;

    ContextThemeWrapper ctw = new ContextThemeWrapper(context, R.style.AppBaseTheme);

    AlertDialog.Builder startGameDialog = new AlertDialog.Builder(ctw);
    startGameDialog.setTitle(getResources().getString(R.string.whats_your_name));

    LinearLayout dialogLayout = new LinearLayout(context);

        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

        dialogLayout.setOrientation(LinearLayout.VERTICAL);

        final EditText newName = new EditText(context);
        newName.setLayoutParams(params);

        newName.setText("");

        final Button submit = new Button(context);
        submit.setText(getString(R.string.done));
        submit.setLayoutParams(params);

    dialogLayout.addView(newName);
    dialogLayout.addView(submit);

    startGameDialog.setView(dialogLayout);
    final Dialog dialog = startGameDialog.create();

    OnClickListener onClick = new OnClickListener() {

        @Override
        public void onClick(View v) {
            GameBoardActivity.NAME = newName.getText().toString();
            dialog.dismiss();
            setUpPlayers();

        }
    };
    submit.setOnClickListener(onClick);     

    dialog.show();
    dialog.setCancelable(false);        

}

尝试的解决方案（均失败）：

使用builder.create()方法构建AlertDialog并设置.setView(dialogLayout, 0, 0, 0, 0)。
先尝试ViewGroup parent = (ViewGroup) dialogLayout.getParent()再尝试删除父级的填充parent.setPadding(0, 0, 0, 0);（这会返回NullPointerException错误，因为您无法为Dialognor设置填充AlertDialog。
