Question

我正在尝试将共享首选项打印到文本视图中，问题是当我尝试保存新的一个时，它会覆盖在previus上。我需要帮助才能让他们成为一个不是压倒一切的时间。

public void loadPicture()
{
    //this is how i load the sharedpreferences on another page.
    gallery.removeAllViews();
    List<String> array =fetchAllPreference();
    for(int i=0;i<array.size();i++)
    {
        TextView iv = new TextView(this);
        LinearLayout.LayoutParams layoutParams=new 
        LinearLayout.LayoutParams(200,200);
        layoutParams.setMargins(10,10,0,0);
        iv.setLayoutParams(layoutParams);
        iv.setText(array.get(i));
        gallery.addView(iv);
    }
}
    //how i save the sharedpreferences
    sendnewword.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            SharedPreferences sharedPref = 
            getSharedPreferences("DictionaryInfo", Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = sharedPref.edit();
            editor.putString("Herbew", Hebrew.getText().toString());
            editor.putString("English", English.getText().toString());
            editor.apply();
            Intent B = new Intent(New_words.this, All_words.class);
            startActivity(B);

        }
    });

//making all sharedpreferences to an array.
public List<String> fetchAllPreference(){
    SharedPreferences sharedPref = getSharedPreferences("DictionaryInfo", 
    Context.MODE_PRIVATE);
    List<String> values = new ArrayList<String>();
    int index = 0;
    Map<String,?> allPrefs = sharedPref.getAll();
    for(Map.Entry<String,?> entry : allPrefs.entrySet()){
        values.add(entry.getValue().toString());
    }
    return values;
}

首先创建JSONArray并在此数组中添加JSONObject。像

chflags nohidden /usr/local/share

享受

使用布局参数打印数组
