        });

        // 设定搜索按钮的响应
        mBtnSearch = (Button) findViewById(R.id.search);

        OnClickListener clickListener = new OnClickListener() {
            public void onClick(View v) {
                SearchButtonProcess(v);
            }
        };

        mBtnSearch.setOnClickListener(clickListener);
    }

    void SearchButtonProcess(View v) {
        if (mBtnSearch.equals(v)) {
            EditText editCity = (EditText) findViewById(R.id.city);
            EditText editSearchKey = (EditText) findViewById(R.id.searchkey);
            mSearch.poiSearchInCity(editCity.getText().toString(),
                    editSearchKey.getText().toString());
        }
    }

    // Override以下方法,管理API
    @Override
    protected void onDestroy() {
        if (mBMapMan != null) {
            mBMapMan.destroy();
            mBMapMan = null;
        }
        super.onDestroy();
    }

    @Override
    protected void onPause() {
        if (mBMapMan != null) {
            mBMapMan.stop();
        }
        super.onPause();
    }

    @Override
    protected void onResume() {
        if (mBMapMan != null) {
            mBMapMan.start();
        }
        super.onResume();
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

　　

运行结果如下：
