【一般的介面跳轉方式如下】

     Intent intent = new Intent(); 
     intent.setClass(HelloworldActivity.this, NextActivity.class);// 這裡強引用了NextActivity
     HelloworldActivity.this.startActivity(intent);

import android.app.Activity;
import android.content.Intent;

/***

public class Navigator {

    public static void navigatorTo(Activity from, final String toActivityName, final Intent intent){
        if(from == null || toActivityName == null || intent == null){
            throw new NullPointerException("from == null || toActivityName == null || intent == null");
        }

        Class<?> clazz = null;
        try {
            clazz = Class.forName(toActivityName);
            if(clazz != null){
                intent.setClass(from, clazz);
                from.startActivity(intent);
            }
        }catch (ClassNotFoundException e){
            e.printStackTrace();
        }
    }

    public static final class ActivityType{
            public static final String ACTIVITY_SECOND = "com.example.administrator.openandroid.SecondActivity";
    }
    
}
 

public class MainActivity extends AppCompatActivity {

    private Activity activity;
    private final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        activity = this;

        findViewById(R.id.text).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.i(TAG, "--onClick--");
                Navigator.navigatorTo(activity, Navigator.ActivityType.ACTIVITY_SECOND, new Intent());
            }
