更改按钮的 OnClickListener 时出现匿名 class 错误
anonymous class error when changing OnClickListener of button
我想在我的 android 应用程序中更改按钮的操作,当我编写这段代码时,出现了一个匿名 class 错误,我不知道为什么。那么你能帮我吗?
错误是:
View.OnClickListener is an anonymous class
代码为:
color_Button.setOnClickListener(new View.OnClickListener(){
public void old_background(View v_1) {
if (v_1.getId() == R.id.button2) {
RelativeLayout background = (RelativeLayout) findViewById(R.id.bg);
ImageButton newButton = (ImageButton)findViewById(R.id.imageButton);
Button color_Button = (Button) findViewById(R.id.button2);
EditText newUsername = (EditText) findViewById(R.id.KidUname);
background.setBackgroundResource(R.drawable.dora);
newButton.setImageResource(R.drawable.flower_2);
color_Button.setBackgroundResource(R.drawable.circle_button);
color_Button.setText("Diego !!");
color_Button.setTextColor(Color.parseColor("#FFFFFFFF"));
newUsername.setHint("Click the flower");
}
}
});
您应该在 onClick()
中编写单击按钮时必须执行的所有代码。在您的代码中,您缺少 onClick()
,因此出现错误。
根据 docs
onClick()
is called when a view has been clicked.
color_Button.setOnClickListener(new View.OnClickListener(){
public void onClick(View v_1) {
if (v_1.getId() == R.id.button2) {
RelativeLayout background = (RelativeLayout) findViewById(R.id.bg);
ImageButton newButton = (ImageButton)findViewById(R.id.imageButton);
Button color_Button = (Button) findViewById(R.id.button2);
EditText newUsername = (EditText) findViewById(R.id.KidUname);
background.setBackgroundResource(R.drawable.dora);
newButton.setImageResource(R.drawable.flower_2);
color_Button.setBackgroundResource(R.drawable.circle_button);
color_Button.setText("Diego !!");
color_Button.setTextColor(Color.parseColor("#FFFFFFFF"));
newUsername.setHint("Click the flower");
}
}
});
