Android 多個Activity 跳轉及傳參

mainActivity 打開 OtherActivity：

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

 

mainActivity 給 OtherActivity 傳參數： 

 

                       Intent intent =  
          new Intent(getApplicationContext(), OtherActivity. 
          class);         
          
             
          // 
          以下二個為OtherActivity傳參數 
          
            intent.putExtra("Name", "eboy"); 
          
            intent.putExtra("Age", 22); 
          
             
          // 
          也可以使用Bundle來傳參數 
          
            Bundle bundle =  
          new Bundle(); 
          
            bundle.putString("Name1", "eboy1"); 
          
            bundle.putInt("Age1", 23); 
          
            intent.putExtras(bundle); 
          
            startActivity(intent); 
         

 

 OtherActivity 接收來自 mainActivity 的參數：

                   Intent intent = getIntent();  
          // 
          用於激活它的意圖對象 
          
         
          
        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關閉時返回一些值，則可使用 startActivityForResult來打開OtherActivity，具體用法以后用到時再了解。
