Android開發(fā)之TextView使用intent傳遞信息，實(shí)現(xiàn)注冊界面功能示例

public class Home extends AppCompatActivity {
  //用于存放個人注冊信息
  EditText user_name ;
  EditText user_code ;
  EditText user_year ;
  EditText user_birth ;
  EditText user_phone ;
  //注冊按鈕 點(diǎn)擊跳轉(zhuǎn)
  Button button01 ;
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);//顯示manLayout
    user_name = (EditText) findViewById(R.id.ed_name);
    user_code = (EditText) findViewById(R.id.ed_code);
    user_year = (EditText) findViewById(R.id.ed_year);
    user_birth = (EditText) findViewById(R.id.ed_birth);
    user_phone = (EditText) findViewById(R.id.ed_phone);
    button01 = (Button) findViewById(R.id.bn_01);
    //通過 intent 實(shí)現(xiàn)活動間的信息傳遞
    button01.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        Intent intent01 = new Intent(Home.this,In.class);
        intent01.putExtra("name",user_name.getText().toString());
        intent01.putExtra("code",user_code.getText().toString());
        intent01.putExtra("year",user_year.getText().toString());
        intent01.putExtra("birth",user_birth.getText().toString());
        intent01.putExtra("phone",user_phone.getText().toString());
        startActivity(intent01);
      }
    });
  }
}
