直接上效果图:
实现步骤:
1.主界面activity_main.xml很简单,一个按钮
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/skin_background" > <Button android:id="@+id/show" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:gravity="center" android:text="退出系统" android:textSize="20sp" /> </RelativeLayout>2.弹出层样式actionsheet.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/transparent" android:orientation="vertical" android:padding="5dp" > <TextView android:id="@+id/title" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/actionsheet_top_normal" android:gravity="center" android:text="@string/title" android:textColor="#8F8F8F" android:textSize="16sp" /> <TextView android:id="@+id/content" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/actionsheet_bottom_selector" android:gravity="center" android:text="@string/content" android:textColor="#FD4A2E" android:textSize="16sp" /> <TextView android:id="@+id/cancel" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@drawable/actionsheet_single_selector" android:gravity="center" android:text="@string/cancel" android:textColor="#037BFF" android:textSize="16sp" /> </LinearLayout>3.ActionSheet类
public class ActionSheet { public interface OnActionSheetSelected { void onClick(int whichButton); } private ActionSheet() { } public static Dialog showSheet(Context context, final OnActionSheetSelected actionSheetSelected, OnCancelListener cancelListener) { final Dialog dlg = new Dialog(context, R.style.ActionSheet); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.actionsheet, null); final int cFullFillWidth = 10000; layout.setMinimumWidth(cFullFillWidth); TextView mContent = (TextView) layout.findViewById(R.id.content); TextView mCancel = (TextView) layout.findViewById(R.id.cancel); mContent.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub actionSheetSelected.onClick(0); dlg.dismiss(); } }); mCancel.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub actionSheetSelected.onClick(1); dlg.dismiss(); } }); Window w = dlg.getWindow(); WindowManager.LayoutParams lp = w.getAttributes(); lp.x = 0; final int cMakeBottom = 0; lp.y = cMakeBottom; lp.gravity = Gravity.CENTER; dlg.onWindowAttributesChanged(lp); dlg.setCanceledOnTouchOutside(false); if (cancelListener != null) dlg.setOnCancelListener(cancelListener); dlg.setContentView(layout); dlg.show(); return dlg; } }4.MainActivity
public class MainActivity extends Activity implements OnActionSheetSelected, OnCancelListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); findViewById(R.id.show).setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub ActionSheet.showSheet(MainActivity.this, MainActivity.this, MainActivity.this); } }); } @Override public void onClick(int whichButton) { // TODO Auto-generated method stub switch (whichButton) { case 0: showToast("确定"); break; case 1: showToast("取消"); break; default: break; } } @Override public void onCancel(DialogInterface dialog) { // TODO Auto-generated method stub showToast("取消"); } private void showToast(CharSequence charSequence) { Toast.makeText(this, charSequence, Toast.LENGTH_SHORT).show(); } }
