如何更改警报对话框的列表视图中的文本颜色？ [英] How to change text color which is there in alert dialog's listview?

问题描述

以下是我的代码，当单击按钮时，显示一个简单的警报对话框

Following is my code to display a simple Alert Dialog, when a button is clicked,

AlertDialog.Builder newImage = new AlertDialog.Builder( MyActivity.this, AlertDialog.THEME_HOLO_LIGHT );
newImage.setTitle( "Select Image" );
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String> (  MyActivity.this, android.R.layout.simple_list_item_1 );
arrayAdapter.add( "Take from camera" );
arrayAdapter.add( "Select from gallery" );

newImage.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() 
{
    @Override
    public void onClick( DialogInterface dialog, int which ) 
    {
    }
});

此代码，显示如下图所示的输出，

This code, display output like below image,

它以白色显示列表项，这就是为什么它不可见的原因。我想将列表项的颜色更改为黑色。

It shows list item in white color, that's why it is not visible. I want to change the list item's color to black.

我应该怎么做？

推荐答案

试试这个

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String> (  MyActivity.this, android.R.layout.simple_list_item_1 ) {
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    View view = super.getView(position, convertView, parent);
    TextView text1 = (TextView) view.findViewById(android.R.id.text1);
    text1.setTextColor(Color.BLACK);
    return view;
  }
};

简单地覆盖 ArrayAdapter 的getview和找到textView更改颜色

Simply override the getview of the ArrayAdapter and find the textView to change the color
