Android选择和设置图片

一、自定义SelectPicPopupWindow类

public class SelectPicPopupWindow extends PopupWindow {   PRivate Button takePhotoBtn, pickPhotoBtn, cancelBtn;   private View mMenuView;   @SuppressLint("InflateParams")   public SelectPicPopupWindow(Context context, OnClickListener itemsOnClick) {      super(context);      LayoutInflater inflater = (LayoutInflater) context            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);      mMenuView = inflater.inflate(R.layout.layout_dialog_pic, null);      takePhotoBtn = (Button) mMenuView.findViewById(R.id.takePhotoBtn);      pickPhotoBtn = (Button) mMenuView.findViewById(R.id.pickPhotoBtn);      cancelBtn = (Button) mMenuView.findViewById(R.id.cancelBtn);      // 设置点击监听      cancelBtn.setOnClickListener(itemsOnClick);      pickPhotoBtn.setOnClickListener(itemsOnClick);      takePhotoBtn.setOnClickListener(itemsOnClick);            this.setContentView(mMenuView);      this.setWidth(LayoutParams.MATCH_PARENT);      this.setHeight(LayoutParams.WRAP_CONTENT);      this.setFocusable(true);      this.setAnimationStyle(R.style.PopupAnimation);       ColorDrawable dw = new ColorDrawable(0x80000000);      this.setBackgroundDrawable(dw);       mMenuView.setOnTouchListener(new OnTouchListener() {         @Override         @SuppressLint("ClickableViewaccessibility")         public boolean onTouch(View v, MotionEvent event) {            int height = mMenuView.findViewById(R.id.pop_layout).getTop();            int y = (int) event.getY();            if (event.getAction() == MotionEvent.ACTION_UP) {               if (y < height) {                  dismiss();               }            }            return true;         }      });   }}
二、自定义布局layout_dialog_pic
    <LinearLayout        android:id="@+id/pop_layout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:background="#ffffff"        android:gravity="center_horizontal"        android:orientation="vertical" >        <Button            android:id="@+id/takePhotoBtn"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_marginLeft="10dip"            android:layout_marginRight="10dip"            android:layout_marginTop="10dp"            android:padding="10dp"            android:text="相机" />        <Button            android:id="@+id/pickPhotoBtn"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_marginLeft="10dip"            android:layout_marginRight="10dip"            android:layout_marginTop="5dp"            android:padding="10dp"            android:text="图库" />        <Button            android:id="@+id/cancelBtn"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_marginBottom="15dip"            android:layout_marginLeft="10dip"            android:layout_marginRight="10dip"            android:layout_marginTop="20dp"            android:padding="10dp"            android:text="取消" />    </LinearLayout></RelativeLayout>
三、具体使用（Button点击调用）
@OnClick  (R.id.iv_makeupinfo_image1)
public void onClick(View view) {             postflage = "1";            menuWindow = new SelectPicPopupWindow(getapplicationContext(), itemsOnClick);            menuWindow.showAtLocation((rlAll),                    Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
}
//为弹出窗口实现监听类private View.OnClickListener itemsOnClick = new View.OnClickListener() {    @Override    public void onClick(View v) {        // 隐藏弹出窗口        menuWindow.dismiss();        switch (v.getId()) {            case R.id.takePhotoBtn:// 拍照                Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");                // 判断存储卡是否可以用，可用进行存储                if (hasSdcard()) {                    intent.putExtra(MediaStore.EXTRA_OUTPUT,                            Uri.fromFile(new File(Environment                                    .getExternalStorageDirectory(), PHOTO_FILE_NAME)));                }                startActivityForResult(intent, PHOTO_REQUEST_CAMERA);                break;            case R.id.pickPhotoBtn:// 相册选择图片                // 激活系统图库，选择一张图片                Intent intent1 = new Intent(Intent.ACTION_PICK);                intent1.setType("image/*");                startActivityForResult(intent1, PHOTO_REQUEST_GALLERY);                break;            case R.id.cancelBtn:// 取消                break;            default:                break;        }    }};
//是否有内存卡private boolean hasSdcard() {    if (Environment.getExternalStorageState().equals(            Environment.MEDIA_MOUNTED)) {        return true;    } else {        return false;    }}
//返回的结果@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {    if (requestCode == PHOTO_REQUEST_GALLERY) {        if (data != null) {            // 得到图片的全路径            Uri uri = data.getData();            crop(uri);        }    } else if (requestCode == PHOTO_REQUEST_CAMERA) {        if (hasSdcard()) {            tempFile = new File(Environment.getExternalStorageDirectory(),                    PHOTO_FILE_NAME);            crop(Uri.fromFile(tempFile));        } else {            Toast.makeText(getApplicationContext(), "未找到存储卡，无法存储照片！", Toast.LENGTH_SHORT).show();        }    } else if (requestCode == PHOTO_REQUEST_CUT) {        try {            //说明从这里获得了bitmap            bitmap = data.getParcelableExtra("data");                //设置上了，说明bitmap获取到了                ivMakeupinfoImage1.setImageBitmap(bitmap);                ivMakeupinfoImage1.setScaleType(ImageView.ScaleType.FIT_XY);              } catch (Exception e) {            e.printStackTrace();        }    }    super.onActivityResult(requestCode, resultCode, data);}
//剪切图片private void crop(Uri uri) {    // 裁剪图片意图    Intent intent = new Intent("com.android.camera.action.CROP");    intent.setDataAndType(uri, "image/*");    intent.putExtra("crop", "true");    // 裁剪框的比例，1：1    intent.putExtra("aspectX", 1);    intent.putExtra("aspectY", 1);    // 裁剪后输出图片的尺寸大小    intent.putExtra("outputX", 200);    intent.putExtra("outputY", 200);    // 图片格式    intent.putExtra("outputFormat", "JPEG");    intent.putExtra("noFaceDetection", true);// 取消人脸识别    intent.putExtra("return-data", true);// true:不返回uri，false：返回uri    startActivityForResult(intent, PHOTO_REQUEST_CUT);}
