intent用法

1.这部分是显示跳转到另一个Activity，这个被跳转的Activ叫做SecondActivity
　写法一：

 Intent intent = new Intent(this,SecondActivity.class);
 intent.putExtra("account",accountText);
 intent.putExtra("password",passwordText);
 startActivity(intent);

　写法二：

ComponentName componentName = new ComponentName("this","SecondActivity.class");
intent.setComponent(componentName);
startActivity(intent);

　　

它其实也就是：

Intent intent = new Intent();

String packageName = this.getPackageName();
String name = SecondActivity.class.getName();
intent.setClassName(packageName,name);

intent.putExtra("account",accountText);
intent.putExtra("password",passwordText);
startActivity(intent);

　

2.这部分是隐式跳转到另一个Activity

Intent intent = new Intent();
intent.setAction("com.example.LOGIN_INFO");
intent.addCategory("android.intent.category.DEFAULT");
intent.putExtra("account",accountText);
intent.putExtra("password",passwordText);
startActivity(intent);

　　

　　

接受类SecondActivity代码：

Intent intent=getIntent();
String account = intent.getStringExtra("account");
String password = intent.getStringExtra("password");

TextView info = findViewById(R.id.info);
info.setText("your name is "+account+",your password is "+password+"");
