吐司选定的切换按钮

Question

我有7 ToggleButtons已创建和一个button。每个命名为星期一，星期二，...星期天。

当我选择("Switch ON")例如星期一和星期四时，我想触摸一个按钮并显示“您已选择星期一和星期四”。

任何想法在MainActivity.java上怎么做？

预先感谢您。

Answer 1

您可以通过为所有七个切换按钮设置onCheckedChangeListener并将其附加到字符串来解决此问题。点击此字符串可以显示。

public class MainActivity extends AppCompatActivity { 

    private ToggleButton toggleButton_Monday; 
    private ToggleButton toggleButton_Thursday,toggleButton_wednesday; 
    private Button buttonSubmit; 

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

    toggleButton_Monday=(ToggleButton)findViewById(R.id.toggleButton1); 
    toggleButton_Thursday=(ToggleButton)findViewById(R.id.toggleButton2); 
    toggleButton_wednesday=(ToggleButton)findViewById(R.id.toggleButton3); 
    buttonSubmit=(Button)findViewById(R.id.button1); 


    buttonSubmit.setOnClickListener(new View.OnClickListener(){ 

     @Override 
     public void onClick(View view) { 
      StringBuilder result = new StringBuilder(); 


      if(toggleButton_Monday.isChecked()) { 

       result.append("Monday "); 
      } 

      if(toggleButton_Thursday.isChecked()) { 

       result.append("Thursday "); 

      } 

      if(toggleButton_wednesday.isChecked()) { 

       result.append("Wednesday "); 

      } 
      //Displaying the message in toast 
      Toast.makeText(getApplicationContext(),"You have selected "+result.toString(),Toast.LENGTH_LONG).show(); 
     } 

    }); 

} 
} 

你可以这样做。
