Activity 间传递对象, 采用Parcelable. 例子如下:
public class FormatEntity implements Parcelable {
public String mAccount;
public String mCode;
public int limitAmount;
public String imeis;
public PrivateFormatEntity() {
super();
}
public PrivateFormatEntity(Parcel source) {
mAccount = source.readString();
mCode = source.readString();
limitAmount = source.readInt();
imeis = source.readString();
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(mAccount);
dest.writeString(mCode);
dest.writeInt(limitAmount);
dest.writeString(imeis);
}
public static final Parcelable.Creator<PrivateFormatEntity> CREATOR = new Creator<PrivateFormatEntity>() {
@Override
public PrivateFormatEntity[] newArray(int size) {
return new PrivateFormatEntity[size];
}
@Override
public PrivateFormatEntity createFromParcel(Parcel source) {
return new PrivateFormatEntity(source);
}
};
}
发送:
FormatEntity youFormat = new FormatEntity();
it.putExtra("yourname", youFormat);
获取:
it.getParcelableExtra("yourname");
在android里面除了使用gallery控件以外，经常使用viewflipper来实现类似的效果，其实viewflipper还能够把一些button，view之类的控件也组织起来进行类似的展示
首先在布局文件里定义：
<ViewFlipper
android:id="@+id/flipper"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
>
</ViewFlipper>核心代码：
LinearLayout layout1 = new LinearLayout(this);
LinearLayout layout2 = new LinearLayout(this);
LinearLayout.LayoutParams lp0 = new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, 1);
material m[] = material.values();
for (int i = 0; i < m.length; i++) {
Button btn = new Button(this);
btn.setText(m[i].toString());
btn.setTag(m[i]);
btn.setOnClickListener(listener);
if (i <= 3)
layout1.addView(btn, lp0);
else
layout2.addView(btn, lp0);
}
flipper.addView(layout1);
flipper.addView(layout2);
flipper.setInAnimation(AnimationUtils.loadAnimation(this,
android.R.anim.slide_in_left));
flipper.setOutAnimation(AnimationUtils.loadAnimation(this,
android.R.anim.slide_out_right));http://www.cmd100.com/bbs/thread-6202-1-1.html
