EditText上的完成按钮监听器？

Question

如果我有一个EditText，并且我想要听用户是否按下键盘上的“完成”按钮，我该怎么做？

Answer 1

代码是

final EditText edittext = (EditText) findViewById(R.id.edittext); 
edittext.setOnKeyListener(new View.OnKeyListener() { 
     public boolean onKey(View v, int keyCode, KeyEvent event) { 
      if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) { 
       Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show(); 
       return true; 
      } 
      return false; 
     } 
    }); 

在这种 '的EditText' 是文本框

Dinash的回答是不错的ID，但它不工作在所有设备上。下面的代码对所有设备

edittext.setOnEditorActionListener(new TextView.OnEditorActionListener() { 
    @Override 
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { 
     if (actionId == EditorInfo.IME_ACTION_DONE) { 
      Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show(); 
      return true; 
     } 
     return false; 
    } 
});

的same Jone答案工作正常，但更换拉姆达：

etPointCombatFirst.setOnEditorActionListener((v, actionId, event) -> { 
       if (actionId == EditorInfo.IME_ACTION_DONE) { 
        Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show(); 
        return true; 
       } 
       return false; 
      });
