Android Intent封装的实例详解

 public void onclick(View view){
    Intent intent=new Intent(this,Main2Activity.class);
    intent.putExtra("text1","xiaoming");
    intent.putExtra("text2","中国人");
    startActivity(intent);
  }

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    ButterKnife.bind(this);
    initView();
  }

  private void initView() {
    String text1 = getIntent().getStringExtra("text1");
    String text2 = getIntent().getStringExtra("text2");
    mTextView.setText(text1);
    mTextView2.setText(text2);
  }

 public void onclick(View view){
    //调用第二个Activity封装好的Intent
    Intent intent = Main2Activity.newIntent(MainActivity.this, "hsis", "wodhis");
    startActivity(intent);
  }

public class Main2Activity extends AppCompatActivity {
  private static final String INTENT_TEXT1="intent_text1";
  private static final String INTENT_TEXT2="intent_text2";

  private String text1,text2;
  @butterknife.Bind(R.id.textView)
  TextView mTextView;
  @butterknife.Bind(R.id.textView2)
  TextView mTextView2;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    ButterKnife.bind(this);
    initIntent();
    initView();
  }
  public static Intent newIntent(Activity activity,String te, String te2){
    Intent intent=new Intent(activity,Main2Activity.class);
