根据条件从另一个微调器填充微调器

我需要做的是如果选择了微调器1中的某个项，它需要在微调器01中显示某个数组，例如，如果微调器选择了一个项目，则红色微调器01需要显示level_array作为微调器的下拉选项，否则显示cparklevel 。 本质上，我试图显示每个停车场有多少级别。 所以微调器1包含停车场名称，微调器01包含级别

Spinner spinner = (Spinner) findViewById(R.id.spinner1); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.cparkColour_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); Spinner spinner2 = (Spinner) findViewById(R.id.Spinner01); if(spinner.getSelectedItem().equals("Red")){ ArrayAdapter adapter1 = ArrayAdapter.createFromResource( this, R.array.level_array, android.R.layout.simple_spinner_item); adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner2.setAdapter(adapter1); } else { ArrayAdapter adapter2 = ArrayAdapter.createFromResource( this, R.array.cparkLevel_array, android.R.layout.simple_spinner_item); adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner2.setAdapter(adapter2); } } 

任何帮助，将不胜感激

这样做：

 spinner_1.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView arg0, View arg1, int position, long arg3) { if(spinner_1.getSelectedItem().equals("Red")){ { // set adapter to spinner_2 here for "Red" selected } else { // set adapter to spinner_2 for "Red" not selected } } @Override public void onNothingSelected(AdapterView arg0) { } });
