Question

首先，对不起我的英语。我是法国人，我搜索了很多，但我找不到解决方案。我是新手。

我想一起使用3个微调器，一个按钮和一个TextView。

我的问题其实是，我不知道如何将它们联系在一起，以便在TextView上给我一个结果。

我向你解释我想要的（你可以看下面我的代码）。

如果用户在SPINNER旋转中选择“markOne”，则只有“modelOne1”和“modelOne2”将出现在SPINNER spin2中，并且只有“colorOne1”和“colorOne2”将出现在SPINNER spin3中。

在SPINNER spin 3中，如果他选择“colorOne1”：按下btn_valid后，“RED”将出现在TextView中。

如果他选择“ColorOne2”：按下btn_valid后，TextView中会出现“BLUE”。

，否则

如果用户在SPINNER旋转中选择“markTwo”，则只有“modelTwo1”和“modelTwo2”将出现在SPINNER spin2中，并且只有“colorTwo1”和“colorTwo2”将出现在SPINNER spin3中。

在SPINNER spin 3中，如果他选择“colorTwo1”：按下btn_valid后，“ORANGE”将出现在TextView中。

如果他选择“ColorTwo2”：按下btn_valid后，“PINK”将出现在TextView中。

我知道这是具体的，并花时间帮助我完成我的代码。我没有找到一个带有3个微调器，按钮，TextView的工作教程，当你是法国人时，它真的很难！

希望你帮帮我。

非常感谢。

public class Main extends AppCompatActivity implements AdapterView.OnItemSelectedListener {

String[] mark = {"markOne","markTwo"};
String[] model = {"modelOne1","modelOne2","modelTwo1","modelTwo2"};
String[] color = {"colorOne1","colorOne2","colorTwo1" ,"colorTwo2"};
private Button btn_valid;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Spinner spin = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, mark);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spin.setAdapter(adapter);
    spin.setOnItemSelectedListener(this);

    Spinner spin2 = (Spinner) findViewById(R.id.spinner2);
    ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, model);
    adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spin2.setAdapter(adapter2);
    spin2.setOnItemSelectedListener(this);

    Spinner spin3 = (Spinner) findViewById(R.id.spinner3);
    ArrayAdapter<String> adapter3 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, color);
    adapter3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spin3.setAdapter(adapter3);
    spin3.setOnItemSelectedListener(this);
}

public void onItemSelected(AdapterView<?> parent, View v, int position, long id ){
}

public void onNothingSelected(AdapterView<?> parent){
}}

嗨朋友我在途中尝试了这段代码我跳了它对你有用

// Class1 is your classname and firstname is your property of class
string localizedName = Testing.GetDisplayName2<Class1, string>(i => i.firstname);

}

Spinner spn1,spn2,spn3;
TextView txtResult;
String spn_1_Selected_item;
Button btnResult;

String[] spinn_mark1 = {"SelectMode","markOne","markTwo"};
String[] spinn_mode2 = {"modelOne1","modelOne2","modelTwo1","modelTwo2"};
String[] spinn_color = {"colorOne1","colorOne2","colorTwo1" ,"colorTwo2"};

ArrayAdapter adapterSpinner_1,adapterSpinner_2,adapterSpinner_3;
