如何在片段自定義視圖中設置唯一的標識

我有三個類，在拼寫錯誤的片段中，我使用我的自定義類StyleAdaptation和SizeAndStyleAdaptation（和SizeAdaptation但忘記了這一個）是相同的類（SizeAndStyle實現只是一個微調字體大小），它們擴展了CardView。如何在片段自定義視圖中設置唯一的標識

而在StyleAdaptation中，我有另一個自定義視圖StyleAndColor，其中有四個用於粗體，斜體，下劃線和最後一個顏色的按鈕。

所以我有一個問題，當我設置upper_style例如我設置粗體，如果我改變片段，並返回這裏的值不保存。但是如果我在更改片段後更改ponc_style並返回，如果我將其設置爲粗體，則兩者（ponc_style和upper_style都設置爲粗體）的問題來自id。

我不知道如何在這種情況下分配唯一的id與childS的一些意見。

當我調用其他類時，TypoFragment.java是我的根片段。

public class TypoFragment extends Fragment { 

    private SizeAdaptation word_space; 
    private SizeAdaptationModel current_word_space = new SizeAdaptationModel(); 
    private SizeAdaptation letter_space; 
    private SizeAdaptationModel current_letter_space = new SizeAdaptationModel();

StyleAdaptation.java是其中i延伸的cardview用於顯示一些字段樣式適應一類

public class StyleAdaptation extends CardView implements IAdaptation {

和StyleAndColor.java擴展了RelativeLayout，其中我只有四個用於粗體，斜體，下劃線和最後一個用於設置文本顏色的按鈕。

謝謝，我有一個例外：android.view.InflateException：二進制XML文件行＃40：二進制XML文件行＃40：錯誤充氣類com.aidodys.profilesCreation.Views.SizeAndStyleAdaptation –

您可以手動保存和恢復的StyleAdaptation

的狀態我已經爲我的自定義視圖類a做了這些nd將我的代碼改編爲您的案例。我沒有跑，因爲我沒有你的代碼，但主要的想法應該是可以理解的：

您應該重寫保存和恢復程序StyleAdaptation，所以他們分開存儲狀態爲每個實例，因爲他們有不同的ID。相同的ID將有他們的孩子，所以你需要手動記住孩子的狀態。

這些行添加到StyleAdaptation類：

protected static class SavedState extends BaseSavedState { 

    private final int style; 

    public SavedState(Parcelable superState, int style) { 
     super(superState); 
     this.style = style; 
    } 

    @Override 
    public void writeToParcel(Parcel out, int flags) { 
     super.writeToParcel(out, flags); 
     out.writeInt(style); 
    } 

    @Override 
    public String toString() { 
     String str = "MyCardView.SavedState{" 
       + Integer.toHexString(System.identityHashCode(this)) 
       + " style=" + style; 
     return str + "}"; 
    } 

    private SavedState(Parcel in) { 
     super(in); 
     style = in.readInt(); 
    } 

    public int getStyle() { 
     return style; 
    } 

    public static final Parcelable.Creator<SavedState> CREATOR = new Creator<SavedState>() { 

     public SavedState createFromParcel(Parcel in) { 
      return new SavedState(in); 
     } 

     public SavedState[] newArray(int size) { 
      return new SavedState[size]; 
     } 

    }; 
} 

@Override 
public void onRestoreInstanceState(Parcelable state) { 
    SavedState savedState = (SavedState) state; 
    super.onRestoreInstanceState(savedState.getSuperState()); 
    style = savedState.getStyle(); 
    listener.onStyleChanged(style); 
} 

@Override 
public Parcelable onSaveInstanceState() { 
    Parcelable result = super.onSaveInstanceState(); 
    return new SavedState(result, style); 
}
