可能重复:
  Android - How to open Activity by clicking button

我想通过按钮从这个(KlikomaniaActivity)打开另一个Activity(GameProcess),但是当我点击按钮时程序崩溃。我不是一个专业的android程序员,请说出我有什么错误:

packagecom.makeandroid.klikomania;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;


public class KlikomaniaActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button Butstart = (Button)findViewById(R.id.butstart);
    final Button Butrez = (Button)findViewById(R.id.butrez);

    Butstart.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Intent intent = new Intent("com.makeandroid.klikomania.GameProcess");
             // эапускаем деятельнсть 
             startService(intent);
        }
    });
}

}

并且在这里GameProcess Acticity:

public class GameProcess extends KlikomaniaActivity {

private static int rezult = 0;
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gameprocess);

        final Button Butklik = (Button)findViewById(R.id.klik);
        final TextView TextTime = (TextView)findViewById(R.id.texttime);
        final TextView TextKolvo = (TextView)findViewById(R.id.kolvo);

        Butklik.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
            rezult=rezult+1;    
            TextKolvo.setText(rezult);
            }
        });
 }
}

1 个答案:

答案 0 :(得分:0)

首先确保您将活动添加到清单文件中:

<activity android:name="com.makeandroid.klikomania.GameProcess"></activity>

第二,开始活动使用此代码:

final Intent gameProcessIntent= new Intent(this, GameProcess.class);
Butstart.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        startActivity(gameProcessIntent);
    }
});

这应该正常工作
