//第一步 权限：

//第二步  在Activity里使用：

                                Log.e("TAG2", "" + catName);

                                e.printStackTrace();
                            }
                        }
                    });
                    Log.d("string", json);
                }
            } catch (MalformedURLException e) {

//然后在点击事件里调用：

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.mButton:
            serchPhone("13777778888");
            break;
    }
}

//我的Activity布局：
