无法在表面0xb14ae7a0上设置EGL_SWAP_BEHAVIOR,错误= EGL_SUCCESS

Question

我不知道为什么它不起作用.无论我在编辑文本上写什么,它总是说同样的事情:"名字"+名称+"已经存在".我只是不知道问题是什么.

public class AddScreen extends AppCompatActivity {
EditText first_name,last_name;
String first,last;
Button add;
Context ctx=this;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_screen);
    first_name=(EditText)findViewById(R.id.firstname);
    last_name=(EditText)findViewById(R.id.lastname);
    add=(Button)findViewById(R.id.save);
    first = first_name.getText().toString();
    last = last_name.getText().toString();

    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DataBaseOperation DB = new DataBaseOperation(ctx);
            Cursor CR=  DB.getInformation(DB);
            CR.moveToFirst();
            boolean status= false;
            String NAME="";
            do {
                if(first.equals(CR.getString(0)) && (last.equals(CR.getString(1))))
                {
                    status=true;
                    NAME=CR.getString(0)+" "+CR.getString(1);
                }
            }while (CR.moveToNext());
            if(status)
            {
                Toast.makeText(getBaseContext(),"THE NAME  "+NAME+"ALREADY EXIST",Toast.LENGTH_LONG).show();
                finish();
            }
            else
            {
                DB.putInformation(DB, first, last);
                Toast.makeText(getBaseContext(),"NEW PLAYER CREATED",Toast.LENGTH_LONG).show();
                finish();

            }
        }

    });
}

它的状态总是如此.我认为问题出在这一行

if(first.equals(CR.getString(0)) && (last.equals(CR.getString(1))))

因为它总是如此.这是logcat
