java – 如果按下键盘上的DONE,如何禁止关闭键盘

这是我的代码(当按下“完成”按钮时设置一个监听器)：

final EditText et = (EditText)findViewById(R.id.et);
et.setOnEditorActionListener(new OnEditorActionListener() 
{        
   @Override
   public boolean onEditorAction(TextView v,int actionId,KeyEvent event)
   {
      if(actionId==EditorInfo.IME_ACTION_DONE)
      {
         if (et.getText().toString().equals(password)) // they entered correct
         {
             // log them in
         }
         else
         {
             // bring up the keyboard
             getWindow().setSoftInputMode(
             WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

             Toast.makeText(Main.this,"Incorrect.",Toast.LENGTH_SHORT).show();
         }
      }
      return false;
   }
});

我意识到,这不行的原因可能是因为它运行这个代码之前,它实际上关闭了自己的软键盘,但这就是为什么我需要帮助.我不知道另一种方式.

一个可能的答案主题可能在于：

activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

那种事情,但我不知道肯定.

解：

EditText et = (EditText)findViewById(R.id.et);
et.setOnEditorActionListener(new OnEditorActionListener() 
{        
  @Override
  public boolean onEditorAction(TextView v,KeyEvent event)
  {
    if(actionId==EditorInfo.IME_ACTION_DONE)
    {
       if (et.getText().toString().equals(password)) // they entered correct
       {
           // log them in
           return false; // close the keyboard
       }
       else
       {
           Toast.makeText(Main.this,Toast.LENGTH_SHORT).show();
           return true; // keep the keyboard up
       }
    }
    // if you don't have the return statements in the if structure above,you
    // could put return true; here to always keep the keyboard up when the "DONE"
    // action is pressed. But with the return statements above,it doesn't matter
    return false; // or return true
  }
});
