當出現鍵盤時隱藏ImageView，並在鍵盤消失時顯示它

Question

如何在鍵盤出現時按下EditText後隱藏ImageView。 然後當鍵盤被解散時再顯示這個ImageView？

Answer 1

我認爲OnFocusChangeListener可能是你正確的選擇。

editText.setOnFocusChangeListener(new OnFocusChangeListener() { 

    @Override 
    public void onFocusChange(View v, boolean hasFocus) { 
     // view/hide ImageView 
    } 
}); 

Answer 2

edit_Text.setOnFocusChangeListener(new OnFocusChangeListener() { 
@Override 
public void onFocusChange(View v, boolean hasFocus) { 
    if(hasFocus){ 
     Toast.makeText(getApplicationContext(), "got the focus", Toast.LENGTH_LONG).show(); 
      // Hide your ImageView 
       iv.setVisibility(View.GONE); // (make the view gone) 
    }else 
     Toast.makeText(getApplicationContext(), "lost the focus", Toast.LENGTH_LONG).show(); 
      // Show your ImageView 
       iv.setVisibility(View.VISIBLE); 
    } 
});
