这是给出错误的 java 文件
package com.example.daksh.timetable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button mon_but,tue_but,wed_but,thur_but,fri_but;
mon_but = (Button)findViewById(R.id.mon);
tue_but = (Button)findViewById(R.id.tue);
wed_but = (Button)findViewById(R.id.wed);
thur_but = (Button)findViewById(R.id.thur);
fri_but = (Button)findViewById(R.id.fri);
final ImageView main_Image = (ImageView) findViewById(R.id.day);
final int[] dayarray = {R.drawable.monday,R.drawable.tuesday,R.drawable.wednesday,R.drawable.thursday, R.drawable.friday};
mon_but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
main_Image.setImageResource(dayarray[0]);
}
});
tue_but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
main_Image.setImageResource(dayarray[1]);
}
});
wed_but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
main_Image.setImageResource(dayarray[2]);
}
});
thur_but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
main_Image.setImageResource(dayarray[3]);
}
});
fri_but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
main_Image.setImageResource(dayarray[4]);
}
});
}
}
我收到的错误如下

请您参考如下方法:
您的 java 文件可能会出现此错误，因为有一个或多个 XML 文件出现错误。
检查所有 XML 文件并解决错误，然后从构建菜单清理或重建项目
从最近编辑的 XML 文件开始
