按钮的setText（）将不实际的setText

Question

我想的setText（）来

Button btnFloor, btnTable; 

这是不工作的ATM，其实我想从

FloorsActivity发送数据 - > TablesActivity - > NewOrdersActivity

那么我如何将数据从活动传递到另一个？

FloorsActivity.java

@Override 
public void onFloorItemClicked(int id) { 


    Intent intent = new Intent(this, TablesActivity.class); 
    intent.putExtra("FloorId", id); 
    startActivity(intent); 

    Toast.makeText(this, "Floor id : " + String.valueOf(id), Toast.LENGTH_SHORT).show(); 

} 

TablesActivity.java

int floorId; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_floors_tables); 
    initViews(); 

    Intent intent = getIntent(); 
    floorId = intent.getIntExtra("FloorId", 1); 
} 

@Override 
public void onTableItemClicked(String name) { 

    String floorName = "F" + floorId; 

    Intent intent = new Intent(this, NewOrderActivity.class); 
    intent.putExtra("FloorId", floorId); 
    intent.putExtra("TableName", name); 
    intent.putExtra("FloorName", floorName); 
    startActivity(intent); 

    Toast.makeText(this, "Table Name : " + String.valueOf(name), Toast.LENGTH_SHORT).show(); 

} 

NewOrderActivity.java

String floorName; 
String tableName; 
int floorId; 

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

    Intent intent = getIntent(); 
    floorName = intent.getStringExtra("FloorName"); 
    tableName = intent.getStringExtra("TableName"); 
    floorId = intent.getIntExtra("FloorId", 1); 
} 

public void initViews() { 

    // Fetch view 
    btnFloor = (Button) findViewById(R.id.btn_floor); 
    btnTable = (Button) findViewById(R.id.btn_table); 

    //Set Views 

    btnFloor.setText(floorName); 
    btnTable.setText(tableName); 

    btnFloor.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent intent = new Intent(NewOrderActivity.this, FloorsActivity.class); 
      startActivity(intent); 
     } 
    }); 

    btnTable.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      Intent intent = new Intent(NewOrderActivity.this, TablesActivity.class); 
      intent.putExtra("FloorId", floorId); 
      startActivity(intent); 

     } 
    });

你叫initViews()你已经超载的意图额外的面前。

固定NewOrderActivity.java：

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

    Intent intent = getIntent(); 
    floorName = intent.getStringExtra("FloorName"); 
    tableName = intent.getStringExtra("TableName"); 
    floorId = intent.getIntExtra("FloorId", 1); 
    initViews(); 
}
