MVC模式入门案例

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity  extends Activity implements MainImplement,
        View.OnClickListener {
    private Button btn;
    private TextView tv_view;
    private MainModel mModel;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mModel = new MainModel();
        btn = (Button) this.findViewById(R.id.btn);
        tv_view = (TextView) this.findViewById(R.id.tv_view);
        btn.setOnClickListener(this);
    }
    @Override
    public void loadData() {
        mModel.loadData(tv_view);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn:
                loadData();
                break;

            default:
                break;
        }
    }
}

import android.widget.TextView;
public class MainModel {
