通过代码添加的Android复选框的外观不正确? [英] Android checkboxes added by code don't have the right appearance?

问题描述

我有一个非常基本的应用程序，我试图在其中插入动态复选框，但我可以让它们显示出来，但是它们没有以正确的样式显示.

I've got a really basic app in which I'm trying to insert dynamic checkboxes, and I can get them to appear, but they're not showing with the correct styling.

请参见下文-Foo根据定义位于LinearLayout中；栏正在以编程方式添加. Foo显示带有灰色框的检查，Bar显示带有白色框.

See below - Foo is in the LinearLayout by definition; Bar is being added programmatically. Foo is showing with a grey box for the check, Bar is showing with a white box.

下面是创建这些代码的代码:

Here's the code that's creating these:

for (Integer i=0; i < arArray.length;i++) {
    CheckBox cb = new CheckBox(getApplicationContext());
    cb.setText("Bar");
    cb.setTextColor(getResources().getColor(android.R.color.black));
    cb.setOnCheckedChangeListener(clListener);
    llDeckChecks.addView(cb);
}

我尝试将drawable设置为某些android.R.drawable类型，但没有与Foo复选框匹配的内容，因此在这一点上我完全感到困惑.

I've tried setting the drawable to some android.R.drawable types, but nothing matches the Foo checkbox, so I'm entirely stumped at this point.

推荐答案

您应该使用活动上下文而不是应用程序上下文来创建按钮.如果使用getApplicationContext()，则不会扩展ContextThemeWrapper.

You should use the activity context to create the button instead of the application context. If you use getApplicationContext() it does not extend ContextThemeWrapper.

尝试更改

CheckBox cb = new CheckBox(getApplicationContext());

到

CheckBox cb = new CheckBox(YourActivity.this); // or getActivity() if in a fragment.
