1.不要利用系统广播创建控件

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY\_SERVICE);

NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

报错：

用第一个方法获取不到焦点：

edit.setOnClickListener(new View.OnClickListener() {
      //有bug，这个方法edit获取不到焦点
        @Override
        public void onClick(View v) {
            isclick = true;
            common.showSoftInput(edit, InformationContentActivity.this);
            if (isFace) {
                isFace = false;
                showCommendWindow(false);
                face.setImageBitmap(common.readBitMap(InformationContentActivity.this, R.drawable.icon_face_hide, false));
            }
        }
    });

用这个方法获取焦点：

edit.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                isclick = true;
                common.showSoftInput(edit, InformationContentActivity.this);
                if (isFace) {
                    isFace = false;
                    showCommendWindow(false);
                    face.setImageBitmap(common.readBitMap(InformationContentActivity.this, R.drawable.icon_face_hide, false));
                }
            }
        }
    });

你有一个自定义的视图中引用XML布局,所需的自定义视图没有把构造函数写完:
