Я относительно новичок в игре для Android, и у меня возникает проблема с зависанием моего приложения при вызове функции из второго класса Java.
это мой основной файл JAVA:
package mashuda.tools.calculator;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Typeface;
import android.os.Bundle;
import android.util.TypedValue;
import android.view.Gravity;
import android.widget.Button;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class CalculatorActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Drawinterface layout = new Drawinterface();
setContentView(layout.drawit());
}
}
и он вызывает этот код:
package mashuda.tools.calculator;

import android.widget.TextView;
public class Drawinterface extends Activity {
/** Called when the activity is first created.
* @return */
TableLayout drawit(){

maintable.setStretchAllColumns(true);
maintable.setShrinkAllColumns(true);

//answer box

answer.setText("ANSWER");
answer.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18);
answer.setBackgroundColor(-1);
answer.setGravity(Gravity.RIGHT);
answer.setTypeface(Typeface.SERIF);
TableRow.LayoutParams params = new TableRow.LayoutParams();
params.span = 5;
//loads answer bar
rowOutput.addView(answer, params);
//first column

multiplykey.setTypeface(Typeface.DEFAULT_BOLD);
// loads keys into second row

//creates 1 key
Button onekey = new Button(this);

// creates 2 key

// loads keys into third row

equalskey.setText("=");
equalskey.setTypeface(Typeface.DEFAULT_BOLD);
// loads keys into fourth row
rowZero.addView(zerokey);
rowZero.addView(decimalkey);
rowZero.addView(negativekey);
rowZero.addView(equalskey);
// loads rows into table
maintable.addView(rowOutput);
maintable.addView(rowSeven);
maintable.addView(rowFour);
maintable.addView(rowOne);
maintable.addView(rowZero);
//sets view as maintable
return (maintable);
}
}
Я добавил второй файл в манифест Android.
и мой компилятор (eclipse) не обнаруживает никаких ошибок.
Любая помощь будет принята с благодарностью
