Java 以编程方式在表中添加新行
我试图解决一个问题，当用户每天完成所有迷你游戏时，创建新行 代码应该将今天的分数保存到变量中（我使用的是SharedReferences），如果前一行的值大于零，则将此变量保存到下一行。 目标是用户可以跟踪其进度。 我所做的是将所有4场比赛的分数保存到一行，同时也保存了今天的日期。我确信像rtsPointsView1，2，3等多个变量都是无用的，我可以用更有效的方式来写，但我不知道怎么写 如何创建正确显示用户进度的表格 MyProgressActivity.javaJava 以编程方式在表中添加新行,java,android,android-layout,Java,Android,Android Layout,我试图解决一个问题，当用户每天完成所有迷你游戏时，创建新行 代码应该将今天的分数保存到变量中（我使用的是SharedReferences），如果前一行的值大于零，则将此变量保存到下一行。 目标是用户可以跟踪其进度。 我所做的是将所有4场比赛的分数保存到一行，同时也保存了今天的日期。我确信像rtsPointsView1，2，3等多个变量都是无用的，我可以用更有效的方式来写，但我不知道怎么写 如何创建正确显示用户进度的表格 MyProgressActivity.java package com.pr

我认为最好的方法是使用ListView并通过ListAdapter进行更新。看看本教程：我认为最好的方法是使用ListView并通过ListAdapter进行更新。请看本教程：
//method for saving. It looks almost the same in every mini-game
private void saveScore() {
SharedPreferences preferences = this.getSharedPreferences(usernameView.getText().toString(), Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putInt("rts_score",player_points);
editor.commit();
}
