點擊註冊按鈕，它必須意向註冊值來註冊類，那麼如果登錄按鈕，按下它必須意向登錄值來註冊類。傳遞價值使用意向

會是怎樣的代碼來執行點擊註冊按鈕，它必須意向註冊值來註冊類，那麼如果登錄按鈕被按下，它必須以登錄值的形式註冊分組秒。

試試這個，

解析值：

MainActivity.java

public class MainActivity extends Activity implements OnClickListener { 

    Button btn; 
    TextView textBox; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     btn = (Button) findViewById(R.id.btn); 
     textBox = (TextView)findViewById(R.id.address); 
     btn.setOnClickListener(this);   
    } 

    @Override 
    public void onClick(View v) { 
     switch (v.getId()) { 
     case R.id.btn: 
      String strTemp = "Test Test"; 
      textBox.setText(strTemp); 

      Intent intent = new Intent(MainActivity.this, Second.class); 
      intent.putExtra("tempstring", strTemp); 
      startActivity(intent); 
      break; 

     default: 
      break; 
     } 
    } 
}

檢索值：

Second.java

public class Second extends Activity { 

    private TextView txtTemp; 

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

     txtTemp = (TextView) findViewById(R.id.txt_temp); 

     Intent intent = getIntent(); 
     String strTemp = intent.getStringExtra("tempstring"); 

     txtTemp.setText(strTemp); 
    } 
}

您可以通過使用intent.putExtra從寄存器活動

Intent i = new Intent(MainActivity.this,Register.class);  
i.putExtra("key_main_m",main_mobile); 
i.putExtra("key_main_p",main_password); 
i.putExtra("Login",true);

在您登錄活動通過這些值的onCreate你可以從捆綁的值類似下面

Bundle extras = getIntent().getExtras(); 
String ph = extras.getString("key_main_m"); 
String pass = extras.getString("key_main_p");

，並檢查值從字符串，並做任何你想要的。
