android – setOnQueryTextFocusChangeListener vs setOnFocusChangeListener

android SearchView有两个方法：setonQueryTextFocuschangelistener和setonFocuschangelistener.它们可以互换吗？他们之间有什么区别？

解决方法

1.“setonFocuschangelistener”(从android.view.View继承)用于整个视图.
2.“setonQueryTextFocuschangelistener”仅适用于AutoCompleteTextView.

查看SearchView的代码：

public void setonQueryTextFocuschangelistener(OnFocuschangelistener listener) {
    mOnQueryTextFocuschangelistener = listener;
}

******

mQueryTextView = (SearchAutoComplete) findViewById(R.id.search_src_text);

******

mQueryTextView.setonFocuschangelistener(new OnFocuschangelistener() {
        public void onFocusChange(View v,boolean hasFocus) {
            if (mOnQueryTextFocuschangelistener != null) {
                mOnQueryTextFocuschangelistener.onFocusChange(SearchView.this,hasFocus);
            }
        }
    });
