我正在製作一個應用程序作爲我的學校項目的一部分，並且我遇到了與「視圖」有關的錯誤。它說'觀點'無法解決。爲什麼看不到解決方案
對R.id.concern和其他人也有另一個錯誤。它說，一個常量表達式是必需的。
這段代碼的一點是，當按下一個按鈕，檢查覈對錶已經查了一下，分配1或0，並不是增加了比分。它比根據分數改變文本。

public class check_Button extends Pop_sallian{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popwindow_sallian);
// Connects The variable to an xml id
TextView output = (TextView) findViewById(R.id.output);
//sets the variable to 0
int score = 0;
public void onCheckboxClicked(View view) {
boolean checked = ((CheckBox) view).isChecked();
switch(view.getId()){
case R.id.concern:
if(checked) {
score += 1;
}
break;
case R.id.faith:
if(checked){
score+=1;
}
break;

if(checked){

case R.id.education:
if(checked){
score+=1;
}
break;
case R.id.community:
if(checked){
score+=1;
}
break;
}
}
// adds the variables together to form a score
if(score == 0){
output.setText("Come on! Get involved, your la sallian community needs you.");
} else if(score == 1){
output.setText("Good start, keep going!");
} else if(score == 2){
output.setText("Room to improve but doing good!");
} else if(score == 3){
output.setText("Very good, others look up to you!");
} else if(score == 4){
output.setText("Wow, you really are an inspiration");
} else if(score == 5){
output.setText("Excellent! You're a leader in your la sallian community");
} else{
output.setText("Unknown");
}
// changes the output text based on score value
}
}
^^代碼中的錯誤是^^

如果你發現有任何改進或其他錯誤，隨意點出來。如果您可以請將代碼作爲您答案的一部分。
爲什麼是android：elevation =「 8dp「中的所有標籤？：o –
你正在面對什麼行號錯誤？什麼是錯誤？你可以請張貼錯誤日誌嗎？ –
這是一個彈出式窗口，我正在嘗試向它添加高程。 –
