如何保存 int 的数据,然后在单击按钮时编辑数字?
我试图拥有它,所以当您单击其中一个答案(Q1A1 或 Q1A2)时,它会向 testScore int 添加一些分数,这样我就可以稍后在稍后的课程中调用它,这样他们得到的分数就会发布在那里。感谢任何提前提供帮助的人!
这是我的代码,
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class Test extends Activity implements OnClickListener
{
TextView Q1A1;
TextView Q1A2;
TextView test;
public static final String PREFS_NAME = "MyPrefsFile";
public static final int testScore = 0;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
Q1A1 = (TextView) findViewById(R.id.Q1A1);
Q1A2 = (TextView) findViewById(R.id.Q1A2);
Q1A1.setOnClickListener(this);
Q1A2.setOnClickListener(this);
test = (TextView) findViewById(R.id.test);
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
test.setText(settings.getString("YourScore", "No Score"));
}
public void onClick(View v)
{
switch(v.getId())
{
case R.id.Q1A1:
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("YourScore", (testScore + 10));
editor.commit();
//Intent FinalScore = new Intent(this, FinalScore.class);
//startActivity(FinalScore);
break;
case R.id.Q1A2:
break;
}
}
}
感谢您的帮助
I am trying to have it so when you click one of the answeers (Q1A1 or Q1A2) it will add a number of points to the testScore int so I can then later call that in a later class so the score they got would be posted there. Thanks to anyone who helps in advance!
here's my code,
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class Test extends Activity implements OnClickListener
{
TextView Q1A1;
TextView Q1A2;
TextView test;
public static final String PREFS_NAME = "MyPrefsFile";
public static final int testScore = 0;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
Q1A1 = (TextView) findViewById(R.id.Q1A1);
Q1A2 = (TextView) findViewById(R.id.Q1A2);
Q1A1.setOnClickListener(this);
Q1A2.setOnClickListener(this);
test = (TextView) findViewById(R.id.test);
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
test.setText(settings.getString("YourScore", "No Score"));
}
public void onClick(View v)
{
switch(v.getId())
{
case R.id.Q1A1:
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("YourScore", (testScore + 10));
editor.commit();
//Intent FinalScore = new Intent(this, FinalScore.class);
//startActivity(FinalScore);
break;
case R.id.Q1A2:
break;
}
}
}
thanks for the help

您将分数保存为整数,但将其作为字符串调用。
更改
test.setText(settings.getString("YourScore" , "No Score"));
测试
.setText(""+settings.getInt("YourScore", 0));
You are are saving your score as an int but calling it as a string.
Change
test.setText(settings.getString("YourScore" , "No Score"));
To
test.setText(""+settings.getInt("YourScore" , 0));
