- 这是点击popupwindows的点击事件
case R.id.tv_pick_phone: Toast.makeText(getActivity(), "从手机相册选择", Toast.LENGTH_SHORT).show(); popupWindow.dismiss(); Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(intent,1); break;
- 点击
- 实现代码(选择图片并进行setImageBitmap加载)
@Override public void onDismiss() { setBackgroundAlpha(1); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); //获取图片路径 if (requestCode == CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK && data != null) { Uri selectedImage = data.getData(); String[] filePathColumns = {MediaStore.Images.Media.DATA}; String path = getImagePath(selectedImage,null); Cursor c = getActivity().getContentResolver().query(selectedImage, filePathColumns, null, null, null); c.moveToFirst(); int index=c.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); String imagePath = c.getString(index); showImage(imagePath); //upload(imagePath);上传功能还没实现 c.close(); } } //加载图片 private void showImage(String imagePath){ Bitmap bm = BitmapFactory.decodeFile(imagePath); ((ImageView)getActivity().findViewById(R.id.head)).setImageBitmap(bm); } private String getImagePath(Uri uri, String seletion) { String path = null; Cursor cursor = getActivity().getContentResolver().query(uri, null, seletion, null, null); if (cursor != null) { if (cursor.moveToFirst()) { path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA)); } cursor.close(); } return path; }
- 贴上圆形头像代码
public class CircleImageView extends android.support.v7.widget.AppCompatImageView { private static final ScaleType SCALE_TYPE = ScaleType.CENTER_CROP; private static final Bitmap.Config BITMAP_CONFIG = Bitmap.Config.ARGB_8888;

} } @Override protected void onDraw(Canvas canvas) { if (getDrawable() == null) { return; } canvas.drawCircle(getWidth() / 2, getHeight() / 2, mDrawableRadius, mBitmapPaint); canvas.drawCircle(getWidth() / 2, getHeight() / 2, mBorderRadius, mBorderPaint);

} else { bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), BITMAP_CONFIG); } Canvas canvas = new Canvas(bitmap); drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());

mBitmapHeight = mBitmap.getHeight(); mBitmapWidth = mBitmap.getWidth(); mBorderRect.set(0, 0, getWidth(), getHeight()); mBorderRadius = Math.min((mBorderRect.height() - mBorderWidth) / 2, (mBorderRect.width() - mBorderWidth) / 2); mDrawableRect.set(mBorderWidth, mBorderWidth, mBorderRect.width() - mBorderWidth, mBorderRect.height() - mBorderWidth); mDrawableRadius = Math.min(mDrawableRect.height() / 2, mDrawableRect.width() / 2); updateShaderMatrix(); invalidate(); } private void updateShaderMatrix() { float scale; float dx = 0; float dy = 0; mShaderMatrix.set(null); if (mBitmapWidth * mDrawableRect.height() > mDrawableRect.width() * mBitmapHeight) { scale = mDrawableRect.height() / (float) mBitmapHeight;

mShaderMatrix.postTranslate((int) (dx + 0.5f) + mBorderWidth, (int) (dy + 0.5f) + mBorderWidth); mBitmapShader.setLocalMatrix(mShaderMatrix); }}
然后在布局里使用
<com.bo.friends.circle.CircleImageView android:id="@+id/head" android:layout_width="120dp" android:layout_height="120dp" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="75dp" />
- 按钮样式代码
drawable\button.xml
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="false" android:drawable="@drawable/sign_seletor_nopressed"/> <item android:state_pressed="true" android:drawable="@drawable/sign_seletor_pressed"/></selector>
drawable\sign_seletor_nopressed.xml
<?xml version="1.0" encoding="UTF-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <!-- 连框颜色值 --><item> <shape> <solid android:color="#17abe3" /> <corners android:radius="20dp" /> </shape></item> <!-- 主体背景颜色值 --> <item android:bottom="1dp" android:right="1dp" android:top="1dp" android:left="1dp"> <shape> <gradient android:startColor="#ffffff" android:centerColor="#ffffff" android:endColor="#ffffff" android:type="linear" android:angle="90" android:centerX="0.5" android:centerY="0.5" /> <padding android:left="2dp" android:top="2dp" android:right="2dp" android:bottom="2dp" /> <!-- 应该是圆角 --> <corners android:radius="20dp" /> </shape> </item></layer-list>
