Android 多个Activity 跳转及传参

mainActivity 打开 OtherActivity：

    Intent intent =  
   new Intent(getApplicationContext(), OtherActivity. 
   class);             
   
startActivity(intent);  
  

 

mainActivity 给 OtherActivity 传参数： 

 

               Intent intent =  
  new Intent(getApplicationContext(), OtherActivity. 
  class);         
  
             
  // 
  以下二个为OtherActivity传参数 
  
            intent.putExtra("Name", "eboy"); 
  
            intent.putExtra("Age", 22); 
  
             
  // 
  也可以使用Bundle来传参数 
  
            Bundle bundle =  
  new Bundle(); 
  
            bundle.putString("Name1", "eboy1"); 
  
            bundle.putInt("Age1", 23); 
  
            intent.putExtras(bundle); 
  
            startActivity(intent); 
 

 

 OtherActivity 接收来自 mainActivity 的参数：

           Intent intent = getIntent();  
  // 
  用于激活它的意图对象 
  
         
  
        String Name = intent.getStringExtra("Name"); 
  
         
  int Age = intent.getIntExtra("Age", 0); 
  
         
  
        Bundle bundle = intent.getExtras();         
  
         
  
        String Name1 = bundle.getString("Name1"); 
  
         
  int Age1 = bundle.getInt("Age1"); 
  
         
  
        TextView textView = (TextView) 
  this.findViewById(R.id.OtherTextView); 
  
        textView.setText(Name + " : " + Age + "/" + Name1 + " : " + Age1); 
 

 

如果mainActivity 需要 OtherActivity关闭时返回一些值，则可使用 startActivityForResult来打开OtherActivity，具体用法以后用到时再了解。
