Android中的原型模式

Android中的应用

Bundle类、Intent类、ArrayList等

Bundle类，该类实现了Cloneable接口

Intent类，该类也实现了Cloneable接口

@Override

public Object clone() {

    return new Intent(this);

}

public Intent(Intent o) {

    this.mAction = o.mAction;

    this.mData = o.mData;

    this.mType = o.mType;

    this.mPackage = o.mPackage;

    this.mComponent = o.mComponent;

    this.mFlags = o.mFlags;

    this.mContentUserHint = o.mContentUserHint;

    if (o.mCategories !=null) {

        this.mCategories =new ArraySet(o.mCategories);}

        if (o.mExtras !=null) {this.mExtras =new Bundle(o.mExtras);}

        if (o.mSourceBounds !=null) {this.mSourceBounds =new Rect(o.mSourceBounds);}

        if (o.mSelector !=null) {this.mSelector =new Intent(o.mSelector);}

        if (o.mClipData !=null) {this.mClipData =new ClipData(o.mClipData);

    }

}

Uri uri = Uri.parse("smsto:10086");

Intent shareIntent =new Intent(Intent.ACTION_SENDTO, uri);

shareIntent.putExtra("sms_body","hello");

Intent intent = (Intent)shareIntent.clone() ;

startActivity(intent);
