如何保存在onCreate方法用户输入 [英] How to save user input in onCreate method

问题描述

我有这个程序，计算每个队多少分了。

所有我想要的是更新比分，当一个或两个团队进入新出现的分数，基本上是一个计划，以确保田径队成绩的。

 公共类LanaLuhm扩展ActionBarActivity {@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.activity_lana_luhm）;    最终的EditText firstTeam =（EditText上）findViewById（R.id.inputFirstTeam）;
    最终的EditText eFirstTeam =（EditText上）findViewById（R.id.textFirstTeam）;
    最终的EditText secondTeam =（EditText上）findViewById（R.id.inpuSecondTeam）;
    最终的EditText eSecondTeam =（EditText上）findViewById（R.id.textSecondTeam）;
    最后的按钮数=（按钮）findViewById（R.id.bCount）;
    count.setOnClickListener（新OnClickListener（）{
        @覆盖
        公共无效的onClick（视图v）{
            // TODO自动生成方法存根
            尝试{
            INT getFirstTeam = Integer.valueOf（firstTeam.getText（）的toString（））;
            INT getSecondTeam = Integer.valueOf（secondTeam.getText（）的toString（））;            eFirstTeam.setText（将String.valueOf（getFirstTeam））;
            eSecondTeam .setText（将String.valueOf（getSecondTeam））;
            }
            赶上（例外五）{
                System.out.print（你不能这样做！）;
            }        }
    }）;}公共无效的onSaveInstanceState（捆绑savedInstanceState）{
}@覆盖
公共布尔onCreateOptionsMenu（菜单菜单）{
    //充气菜单;如果是present这增加了项目操作栏。
    。getMenuInflater（）膨胀（R.menu.lana_luhm，菜单）;
    返回true;
}@覆盖
公共布尔onOptionsItemSelected（菜单项项）{
    //处理动作栏项目点击这里。操作栏会
    //自动处理上点击主页/向上按钮，只要
    //你在AndroidManifest.xml中指定一个父活动。
    INT ID = item.getItemId（）;
    如果（ID == R.id.action_settings）{
        返回true;
    }
    返回super.onOptionsItemSelected（项目）;
}
}
 

解决方案

您可以使用共享preferences 拯救球队成绩。

  //为了节省球队得分
共享preferences设置= preferenceManager.getDefaultShared preferences（本）;
共享preferences.Editor E = settings.edit（）;e.putString（teamScore1，firstTeam.getText（）的toString（））; //第一阵容
e.putString（teamScore2，secondTeam.getText（）的toString（））; //第二阵容e.commit（）;//获得队将比分
串TEAM1 = settings.getString（teamScore1，）;
串TEAM2 = settings.getString（teamScore2，）;
 

I have this program that counts how many points each team has.

All what I want is that updating the score when one or two teams enter there new scores, basically a program to keep track of teams scores.

public class LanaLuhm extends ActionBarActivity {

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

    final EditText firstTeam= (EditText) findViewById(R.id.inputFirstTeam);
    final EditText eFirstTeam= (EditText) findViewById(R.id.textFirstTeam);


    final EditText secondTeam= (EditText) findViewById(R.id.inpuSecondTeam);
    final EditText eSecondTeam = (EditText) findViewById(R.id.textSecondTeam);


    final Button count = (Button) findViewById(R.id.bCount);
    count.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            try{
            int getFirstTeam = Integer.valueOf(firstTeam.getText().toString());
            int getSecondTeam = Integer.valueOf(secondTeam.getText().toString());

            eFirstTeam.setText(String.valueOf(getFirstTeam ));
            eSecondTeam .setText(String.valueOf(getSecondTeam ));
            }
            catch(Exception e){
                System.out.print("you can't do that!"); 
            }

        }
    });



}

public void onSaveInstanceState(Bundle savedInstanceState){


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.lana_luhm, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

解决方案

You can use SharedPreferences to save team scores.

//To save team score
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor e = settings.edit();

e.putString("teamScore1", firstTeam.getText().toString()); //1st Team
e.putString("teamScore2", secondTeam.getText().toString()); //2nd Team

e.commit();

//Retrieve team score
String team1 = settings.getString("teamScore1", "");
String team2 = settings.getString("teamScore2", "");
