Android 当用户单击按钮时显示列表视图

我做了一个迷你冒险游戏，玩家可以去北方、南方、东方、西方等等

现在我想让播放器保存一个清单，但我不知道如何制作GUI。我希望在用户单击inventory按钮时显示一个

列表视图

视图的代码如下所示

我从答案中尝试了以下代码，但它没有任何作用

ListView DynamicListView = new ListView(this);

final String[] DynamicListElements = new String[] {
        "Hello",
        "Hi",
        "Android Studio",
        "Java"
};

ArrayAdapter adapter = new ArrayAdapter (AdventureActivity.this, android.R.layout.simple_list_item_1, DynamicListElements);
DynamicListView.setAdapter(adapter);



TableRow element1 = (TableRow) findViewById(R.id.tableRow3);
element1.addView(DynamicListView);

如果您认为活动名称不同于MainActivity，请相应地更改它。在本例中，我使用MainActivity.this

ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, DynamicListElements);

DynamicListView.setAdapter(adapter);

linearLayout.addView(DynamicListView);

//this may not be needed if you are using exisitng layout
this.setContentView(linearLayout, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

ArrayAdapter=新的ArrayAdapter（MainActivity.this，android.R.layout.simple\u list\u item\u 1，DynamicListElements）；
DynamicListView.setAdapter（适配器）；
linearLayout.addView（DynamicList视图）；
//如果您使用的是现有布局，则可能不需要这样做
this.setContentView（linearLayout，newlinearLayout.LayoutParams（LayoutParams.MATCH_PARENT，LayoutParams.MATCH_PARENT））；

您是否尝试过以编程方式创建它，然后将其添加到布局中？@ManjunathaMuniyappa我不知道怎么做。没有好的例子。或者，如果你能找到一个示例教程，那么我想要它。suer，我正在添加一个示例我使用现有的TableLayout。我不知道为什么它不起作用。它使一半的视图变成黑色。我用我的发现更新了这个问题。我尝试将ListView添加到TableLayout和TableRow中，但没有成功。我想我一定是做错了什么，但我不明白。

//create a new layout or use if you have one
LinearLayout linearLayout = new LinearLayout(this);

//creating listview dynamically
ListView DynamicListView = new ListView(this);

//lit items. Hardcoded here, you can set the values dynamically using ArrayList

final String[] DynamicListElements = new String[] {"Hello","Hi","Android Studio","Java"};

ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, DynamicListElements);

DynamicListView.setAdapter(adapter);

linearLayout.addView(DynamicListView);

//this may not be needed if you are using exisitng layout
this.setContentView(linearLayout, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
