EditText獲取焦點監聽事件_EditText獲取和失去焦點操作

今天在做搜索框的時候、遇到需要獲取焦點之后做一些事情、實現方法也很簡單、那就是綁定OnFocusChangeListener事件、實現 onFocusChange(View v, boolean hasFocus) 方法、第二個參數就是判斷得到焦點或失去焦點、從而實現我得想要的效果、代碼如下：

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) {
            // 此處為得到焦點時的處理內容
        } else {
            // 此處為失去焦點時的處理內容
        }
    }
});

文本框重新獲得焦點方法如下

searchView.setFocusable(true);
searchView.setFocusableInTouchMode(true);
searchView.requestFocus();
 
searchView.clearFocus();//失去焦點
searchView.requestFocus();//獲取焦點

 

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;
            }
        });
