你面临的问题是什么？ – SaravInfern

我想让2个相同的按钮在不同的旋钮中存储2个不同的文本 – Marroquino

您是否打算在任何时候使用'sp2.setAdapter'？ –

答

你只需要安装适配器和微调的一次。

无论你试图点击事件之间的事，只是被添加到onItemSelected，但为了设置其他微调的选择，它需要一些数据，所以一个适配器添加到它。

而且，为了您对问题的最新编辑，您没有正确缩进代码，但是您已在按钮的onClick之内设置了一些不应该在其中的东西。

public class MainActivity extends AppCompatActivity { 

    List<String> pn, txt; 
    Spinner sp1, sp2; 
    Button b, b1, b2, b3; 
    EditText et, et1; 

    ArrayAdapter<String> adp1, adp2; // Added 

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

     setupSpinners(); 

     b = (Button) findViewById(R.id.button); 
     b1 = (Button) findViewById(R.id.button1); 
     b2 = (Button) findViewById(R.id.button2); 
     b3 = (Button) findViewById(R.id.button3); 
     et = (EditText) findViewById(R.id.editText); 
     et1 = (EditText) findViewById(R.id.editText1); 

     b.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       adp1.add(et.getText().toString()); // Changed 
       et.setText(""); 
      } 
     }); 

     b2.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       adp2.add(et1.getText().toString()); 
       et1.setText(""); 
      } 
     }); 
    } 

    public void setupSpinners() { 

     sp1 = (Spinner) findViewById(R.id.spinner); 
     sp2 = (Spinner) findViewById(R.id.spinner1); 
     pn = new ArrayList<String>(); 
     txt = new ArrayList<String>(); 
     txt.add("Sorry Boss I'cant go today i'm sick"); 
     pn.add("123456789"); 

     adp1 = new ArrayAdapter<String>(this, 
       android.R.layout.simple_dropdown_item_1line, pn); 
     adp2 = new ArrayAdapter<String>(this, 
       android.R.layout.simple_dropdown_item_1line, txt); 

     sp1.setAdapter(adp1); 
     sp1.setSelection((pn.size() - 1)); 
     sp1.setOnItemSelectedListener(new OnItemSelectedListener() { 

      @Override 
      public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
       sp2.setSelection(arg2); 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> arg0) { 
      } 
     }); 

     sp2.setAdapter(adp2); 

    } 
}
