通过编程创建的网格视图内容的文本颜色 [英] Text color by programmatically created grid view content

问题描述

我了解如何在设计视图中执行此操作，但是我不确定如何基于以编程方式创建的元素来创建样式.我遵循了教程，这是我的位置:

I understand how to do this in design view, but I'm not sure how to create a style based on programmatically created elements. I followed a tutorial and here's where I'm at:

我有一个网格视图，该视图由一个字符串数组填充，如下面的代码所示:

I have a grid view which is populated by a string array as in the code below:

...
gridView = (GridView) findViewById(R.id.gridView);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, strData);
gridView.setAdapter(adapter);

字符串数组的每个元素都会很好地填充网格.

Each element of the string array populates the grid just fine.

如何设置添加到gridView的项目的文本颜色?

How would I set the text color of the items added to the gridView?

推荐答案

2个解决方案:动态或具有自定义布局.

2 solutions: dynamically or with a custom layout.

• 动态:当您在ArrayAdapter中覆盖getView()方法时，可以使用setTextColor(...)设置文本颜色，如下所示:

• Dynamically: you can set a text color by using setTextColor(...) when you Override the getView() method in your ArrayAdapter, something like this:

gridview.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, strData) {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView text = (TextView) view.findViewById(android.R.id.text1);
        text.setTextColor(getResources().getColor(R.color.my_color));
        return view;
    }
});

自定义布局:这是最简单的方法，将自定义布局构建为:

Custom Layout: this is the simplest way, build a custom layout as:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tv"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:textColor="@color/my_color"
    android:background="@drawable/my_background"
    android:padding="5sp"
    android:singleLine="true"
    android:gravity="center" />  

然后，将其设置为您的适配器:

Then, set it to your adapter:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.my_layout_above, strData);

即使您动态地希望这样做，我也不确定，但是我认为最好使用自定义布局.
希望这会有所帮助.

Even if, you wanted this dynamically, I'm not sure but I think it's better to do with a custom layout.
Hope this helps.
