使用Intent在不同activity間進(jìn)行傳參的兩種方法

• 使用Intent的putExtra()方法進(jìn)行參數(shù)傳遞

傳遞參數(shù)

  Intent intent = new Intent(FromActivity.this, ToActivity.class);
  /*設(shè)置inent的傳遞參數(shù)*/
  intent.putExtra("args", args);
  startActivity(intent);

接收參數(shù)

  // 接收傳入的intent對(duì)象
  Intent intent = getIntent();
  if(intent != null){
      //獲取intent中的參數(shù)
      String regAccount = intent.getStringExtra("args");
  }

• 使用Bundle對(duì)象將參數(shù)封裝進(jìn)行傳遞

封裝并傳遞參數(shù)

  Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
  // 使用Bundle對(duì)象進(jìn)行傳參,做一層封裝
  Bundle bundle = new Bundle();
  bundle.putString("accountName",accountName);
  bundle.putInt("accountAge",accountAge);
  // intent對(duì)象綁定bundle對(duì)象
  intent.putExtras(bundle);
  startActivity(intent);

接收參數(shù)

  // 接受傳入的intent對(duì)象
  Intent intent = getIntent();
  if(intent != null){
    // 獲取Bundle對(duì)象中的參數(shù)
    Bundle bundle = intent.getExtras();
    if(bundle != null){
        String accountName = bundle.getString("accountName", "");
        Int accountAge = bundle.getInt("accountAge", 1);
    }
