[英]android spinner and array adapter programmatically
I am trying to programmatically create a Spinner using an ArrayAdapter. 我试图使用ArrayAdapter以编程方式创建一个Spinner。 This is being done in a closed source jar as part of an Android library project and I do not have any access to resources. 这是在一个封闭的源jar中完成的,作为Android库项目的一部分,我没有任何资源访问权限。
I want to know how to customize the layout and the text view that displays the spinner. 我想知道如何自定义布局和显示微调器的文本视图。
--EDIT-- - 编辑 -
Presently I am using the following code 目前我正在使用以下代码
ArrayAdapter<T> spinnerData = new ArrayAdapter<T>(this, Android.R.layout.simple_spinner_item, T[]);
spinner.setAdapter(spinnerData);
What is happening is that I cannot control the size of the fonts, colours or anything else. 发生的事情是我无法控制字体,颜色或其他任何东西的大小。 When I click on the spinner to select something all the options are in really small text. 当我点击微调器选择某些东西时,所有选项都是非常小的文本。 I want to be able to change the way it renders on screen. 我希望能够改变它在屏幕上呈现的方式。
Just create a custom ArrayAdapter and define how the spinner textview should look in that getDropDownView method of the adapter 只需创建一个自定义ArrayAdapter并定义微调器textview在适配器的getDropDownView方法中的外观
public class CustomizedSpinnerAdapter extends ArrayAdapter<String> {
private Activity context;
String[] data = null;
public CustomizedSpinnerAdapter(Activity context, int resource, String[] data2)
{
super(context, resource, data2);
this.context = context;
this.data = data2;
}
...
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if(row == null)
{
//inflate your customlayout for the textview
LayoutInflater inflater = context.getLayoutInflater();
row = inflater.inflate(R.layout.spinner_layout, parent, false);
}
//put the data in it
String item = data[position];
if(item != null)
{
TextView text1 = (TextView) row.findViewById(R.id.rowText);
text1.setTextColor(Color.WHITE);
text1.setText(item);
}
return row;
}
...
}
and set this adapter for the spinner 并为微调器设置此适配器
Spinner mySpinner = (Spinner) findViewById(R.id.mySpinner);
final String[] data = getResources().getStringArray(
R.array.data);
final ArrayAdapter<String> adapter1 = new CustomizedSpinnerAdapter(
AddSlaveActivity.this, android.R.layout.simple_spinner_item,
data);
mySpinner.setAdapter(adapter1);
