android popupwindow

直接上代码

public class MainActivity extends Activity implements OnClickListener {private Button btnPopup;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btnPopup = (Button) findViewById(R.id.btn);btnPopup.setOnClickListener(this);}public void onClick(View v) {showDialog();}private void showDialog() {View view = getLayoutInflater().inflate(R.layout.photo_choose_dialog, null);Dialog dialog = new Dialog(this, R.style.transparentFrameWindowStyle);dialog.setContentView(view, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));Window window = dialog.getWindow();// 设置显示动画window.setWindowAnimations(R.style.main_menu_animstyle);WindowManager.LayoutParams wl = window.getAttributes();wl.x = 0;wl.y = getWindowManager().getDefaultDisplay().getHeight();// 以下这两句是为了保证按钮可以水平满屏wl.width = ViewGroup.LayoutParams.MATCH_PARENT;wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;// 设置显示位置dialog.onWindowAttributesChanged(wl);// 设置点击外围解散dialog.setCanceledOnTouchOutside(true);dialog.show();}}

activity_main.xml 的布局文件就不上传了就一个button， photo_choose_dialog.xml 布局文件：

<?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="match_parent"    android:background="#00000000"    android:gravity="bottom"    android:orientation="vertical"    android:padding="5dip" >    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/photo_gallery_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:text="图库"        android:textSize="16sp" />    <TextView        android:layout_width="match_parent"        android:layout_height="0.5dip"        android:background="#DAD9DB" />    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/photo_camera_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:text="拍照"        android:textSize="16sp" />    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="5dip"        android:background="@drawable/photo_cancel_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:text="取消"        android:textSize="16sp" /></LinearLayout>

弹出的效果图

图中button 设置了圆角

style 文件：

<?xml version="1.0" encoding="utf-8"?><resources>    <style name="transparentFrameWindowStyle" parent="android:style/Theme.Dialog">        <item name="android:windowBackground">@drawable/photo_choose_bg</item>    </style>    <style name="main_menu_animstyle">        <item name="android:windowEnterAnimation">@anim/photo_dialog_in_anim</item>        <item name="android:windowExitAnimation">@anim/photo_dialog_out_anim</item>    </style></resources>
