EditText获取焦点监听事件_EditText获取和失去焦点操作

今天在做搜索框的时候、遇到需要获取焦点之后做一些事情、实现方法也很简单、那就是绑定OnFocusChangeListener事件、实现 onFocusChange(View v, boolean hasFocus) 方法、第二个参数就是判断得到焦点或失去焦点、从而实现我得想要的效果、代码如下：

EditText searchView = (EditText) findViewById(R.id.search_text);
searchView.setOnFocusChangeListener(new android.view.View.
        OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            // 此处为得到焦点时的处理内容
        } else {
            // 此处为失去焦点时的处理内容
        }
    }
});

文本框重新获得焦点方法如下

searchView.setFocusable(true);
searchView.setFocusableInTouchMode(true);
searchView.requestFocus();

searchView.clearFocus();//失去焦点
searchView.requestFocus();//获取焦点

EditText et = (EditText) findViewById(R.id.et);
        et.clearFocus();
        et.setFocusable(false);

searchEdit.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-generated method stub
                searchEdit.setFocusable(true);
                searchEdit.setFocusableInTouchMode(true);
                searchEdit.requestFocus();
                Intent intent = new Intent(getActivity(),SearchActivity.class);
                startActivity(intent);
                return false;
            }
        });
