waiting for reply..
It clearly shows "java.lang.ArithmeticException: / by zero", maybe you didn't set mCroppedWidthWeight.
I think you should debug FixedRatioCroppedTextureView.onMeasure() method to have a look yourself.
Following class is to create custome square view framelayout
public class FixedAspectRatioFrameLayout extends FrameLayout
{
private int mAspectRatioWidth;
private int mAspectRatioHeight;
public FixedAspectRatioFrameLayout(Context context)
{
super(context);
}
public FixedAspectRatioFrameLayout(Context context, AttributeSet attrs)
{
super(context, attrs);
init(context, attrs);
}
public FixedAspectRatioFrameLayout(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
init(context, attrs);
}
private void init(Context context, AttributeSet attrs)
{
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.FixedAspectRatioFrameLayout);
mAspectRatioWidth = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspect_ratio_width, 1);
mAspectRatioHeight = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspect_ratio_height, 1);
a.recycle();
}
// **overrides**
@Override protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)
{
int originalWidth = MeasureSpec.getSize(widthMeasureSpec);
int originalHeight = MeasureSpec.getSize(heightMeasureSpec);
int calculatedHeight = originalWidth * mAspectRatioHeight / mAspectRatioWidth;
int finalWidth, finalHeight;
if (calculatedHeight > originalHeight)
{
finalWidth = originalHeight * mAspectRatioWidth / mAspectRatioHeight;
finalHeight = originalHeight;
}
else
{
finalWidth = originalWidth;
finalHeight = calculatedHeight;
}
super.onMeasure(
MeasureSpec.makeMeasureSpec(finalWidth, MeasureSpec.EXACTLY),
MeasureSpec.makeMeasureSpec(finalHeight, MeasureSpec.EXACTLY));
}
}
Desing test layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="@+id/topContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@color/colorPrimary"
android:orientation="vertical">
<customecamera.com.ffmpegcamera.FixedAspectRatioFrameLayout
android:layout_gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/pick_imageview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:src="@mipmap/ic_launcher" />
</customecamera.com.ffmpegcamera.FixedAspectRatioFrameLayout>
</LinearLayout>
<LinearLayout

</customecamera.com.ffmpegcamera.FixedAspectRatioFrameLayout>
</RelativeLayout>
</LinearLayout>
</LinearLayout>
and else part i have added from your sample project
i have set width to match parent and on measure i am getting device width
i have given 1:1 for mAspectRatioWidth and mAspectRatioHeight
but still it show error
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.FixedAspectRatioFrameLayout);
mAspectRatioWidth = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspect_ratio_width, 1);
mAspectRatioHeight = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspect_ratio_height, 1);
a.recycle();
Check the value of FixedRatioCroppedTextureView.mCroppedWidthWeight when onMeasure is called.
check out screen shot
its getting zero
got solved now not crashing
thank you for help..
